Iran: History, Government & Society

Iran is a revisionist middle power whose foreign policy is set less by its elected president than by Supreme Leader Ali Khamenei, the Islamic Revolutionary Guard Corps, and the national security institutions around them; President Masoud Pezeshkian took office in July 2024 after winning the snap presidential election, but the constitutional system leaves ultimate authority over defense, regional policy, and strategic questions with the Supreme Leader and bodies under his influence Iranian Constitution, English translation Reuters Encyclopaedia Britannica. Politically, Iran is a theocratic republic with elected institutions constrained by clerical oversight, especially the Supreme Leader and Guardian Council, which vets candidates and can narrow the field before voters ever cast ballots Iranian Constitution, English translation Freedom House.

The current government is formally headed by Pezeshkian, and his cabinet includes Foreign Minister Abbas Araghchi, who was approved by parliament in August 2024; the administration is usually described as reformist-leaning or pragmatic, but it operates inside a system still dominated by conservative clerical and security centers of power Reuters Reuters. In practice, no Iranian government can make durable foreign-policy changes without assent from Khamenei and the security establishment, which is why Tehran can signal tactical flexibility on diplomacy while holding firm on deterrence, missile development, and support for regional armed partners International Crisis Group Council on Foreign Relations.

Iran’s place in the world today is defined by isolation from the United States and much of Europe, growing alignment with Russia and China, and a strategy of building leverage through regional networks and strategic geography rather than through conventional economic weight alone U.S. Department of State Ministry of Foreign Affairs of the People’s Republic of China President of Russia. Iran joined the Shanghai Cooperation Organisation in 2023, has deepened military and political coordination with Moscow, and treats its partnerships with China and Russia as insurance against Western pressure, even while neither partner offers a full substitute for access to Western finance and technology Shanghai Cooperation Organisation Reuters Atlantic Council. Its regional posture remains shaped by deterrence against Israel and the United States, influence in Iraq, Syria, Lebanon, and Yemen, and the constant importance of the Gulf and Strait of Hormuz to its security calculus CSIS U.S. Energy Information Administration.

Economically, Iran is a large but constrained hydrocarbon state. The World Bank estimated GDP at about $401 billion in current U.S. dollars in 2023, while oil, gas, petrochemicals, metals, and a sizable domestic market remain the backbone of the economy World Bank U.S. Energy Information Administration. Iran holds some of the world’s largest proved oil and natural gas reserves, but U.S. sanctions, banking restrictions, and chronic underinvestment have limited export revenue, weakened the currency, and pushed Tehran toward sanctions-evasion networks and deeper trade with Asian buyers, especially China U.S. Energy Information Administration OFAC, U.S. Treasury IMF. Inflation, unemployment, and fiscal stress matter in foreign policy because they make sanctions relief and export access economically valuable, but regime survival still outranks economic normalization when the two collide World Bank International Crisis Group.

Three issues define Iran’s current trajectory. First is the nuclear file: Tehran insists its program is peaceful, but the IAEA has repeatedly reported high-level uranium enrichment and unresolved safeguards issues, making the nuclear program the central driver of sanctions risk and crisis diplomacy IAEA Board of Governors report GOV/2024/29 Reuters. Second is regional deterrence and proxy warfare: Iran continues to rely on missiles, drones, and aligned non-state partners as cost-effective tools to deter stronger adversaries and project influence below the threshold of direct full-scale war CFR CSIS. Third is domestic legitimacy. Low turnout in recent elections

Current Iranian foreign and domestic policy still runs through the settlement created by the 1979 Islamic Revolution: a republican state with elected institutions, but one constitutionally subordinated to clerical oversight under the Supreme Leader and bodies such as the Guardian Council and Expediency Council Constitute Project, Constitution of the Islamic Republic of Iran. That order was built against the memory of foreign interference, above all the 1953 coup that removed Prime Minister Mohammad Mosaddegh after his oil nationalization drive; the U.S. government’s own declassified record states that the coup was carried out under CIA direction as TPAJAX U.S. Department of State, Foreign Relations of the United States, 1952–1954, Iran, 1951–1954. For today’s leadership, that episode is not background rhetoric but a core regime-security lesson: Western pressure is read through a precedent in which economic conflict, covert action, and regime change were linked U.S. Department of State Constitute Project.

The second founding trauma is the Iran-Iraq War of 1980–1988. Iran’s leadership still treats that war as proof that strategic loneliness is more dangerous than international isolation: Iraq invaded in September 1980, and the conflict ended only after UN Security Council Resolution 598 and vast human and economic losses UN Peacemaker, Security Council Resolution 598 (1987) Encyclopaedia Iranica, IRAQ vii. IRAN-IRAQ WAR. The war’s legacy shaped three enduring policies: insistence on indigenous missile and defense industries, preference for partner militias and forward deterrence beyond Iran’s borders, and deep suspicion of outside security guarantees International Crisis Group, Iran’s Priorities in a Turbulent Middle East Arms Control Association, Missile Chronology: Iran. When Iranian officials invoke the “Sacred Defense,” they are not just commemorating sacrifice; they are justifying a doctrine of self-reliance and layered deterrence that still drives regional policy Encyclopaedia Iranica.

A third inflection point was the post-1989 reconstruction and the long cycle of sanctions and nuclear diplomacy that followed. After Ayatollah Khomeini’s death in 1989, constitutional revision strengthened the presidency’s administrative role while preserving ultimate authority for the Supreme Leader Constitute Project. The nuclear file then became the main arena where Iran tried to reconcile regime survival, technological status, and economic access. The 2015 Joint Comprehensive Plan of Action traded nuclear restraints for sanctions relief, as laid out in UN Security Council Resolution 2231 and the IAEA’s verification framework UN Security Council Resolution 2231 (2015) IAEA, Verification and Monitoring in the Islamic Republic of Iran in light of United Nations Security Council Resolution 2231 (2015). The U.S. withdrawal from the deal in 2018 and the reimposition of sanctions reinforced the argument, powerful across Iran’s political spectrum, that Western commitments are reversible and that economic dependence creates strategic vulnerability U.S. Department of State, Remarks on the Joint Comprehensive Plan of Action International Atomic Energy Agency.

The historical narratives current leaders reach for are therefore consistent and highly usable in policy. One is resistance to domination: from 1953 to sanctions, the state presents itself as defending sovereignty against coercion by the United States and its partners U.S. Department of State UN Security Council Resolution 2231 (2015). The other is “strategic patience” backed by deterrence: the lesson drawn from the Iran-Iraq War and decades of pressure is that Iran must absorb shocks, avoid capitulation, and build leverage through missiles, nuclear latency, and regional networks rather than rely on outside protection International Crisis Group Arms Control Association. Those narratives help explain a system that can permit elections and tactical diplomacy while remaining structurally hostile to any settlement it sees as threatening regime continuity or strategic autonomy Constitute Project.

Iran’s political system is dual-track: elected republican institutions exist, but the decisive authority sits above them in the office of the Supreme Leader. The constitution gives the Supreme Leader command over the armed forces, power to appoint the head of the judiciary, state broadcasting chief, and half of the Guardian Council, plus broad authority to set the system’s “general policies” Constitute Project: Constitution of Iran, 1989 revision. Ayatollah Ali Khamenei remains head of state and the ultimate foreign- and security-policy arbiter, while President Masoud Pezeshkian took office in July 2024 after winning the runoff in the snap presidential election held following President Ebrahim Raisi’s death Encyclopaedia Britannica: Ali Khamenei Iran Ministry of Interior election reports via IRNA Reuters, July 6 2024. In practice, the president runs the cabinet and day-to-day economic administration, but on core questions of regime security, nuclear policy, and the use of force, elected institutions operate inside limits set by the Leader and the security establishment Carnegie Endowment for International Peace Constitute Project: Constitution of Iran, 1989 revision.

The institutional structure is designed to filter electoral competition rather than permit open alternation in power. Iran elects a president, a unicameral parliament called the Islamic Consultative Assembly, local councils, and the Assembly of Experts, but candidate vetting by the 12-member Guardian Council sharply narrows who can run Constitute Project: Constitution of Iran, 1989 revision. In the March 2024 parliamentary election, conservative and hardline factions retained control after another heavily managed contest in which many reformist and moderate figures were disqualified; official turnout was reported at 41%, the lowest in the Islamic Republic’s parliamentary history according to state figures cited by international reporting Reuters, March 2 2024 AP News, March 2 2024. Pezeshkian’s 2024 presidential win showed that the system still allows limited correction when legitimacy is under strain, but not a transfer of power away from the Islamic Republic’s core unelected institutions International Crisis Group Reuters, July 6 2024.

The ruling coalition is therefore not a normal governing majority but a negotiated balance among the Supreme Leader’s office, the Islamic Revolutionary Guard Corps, conservative clerical networks, parliament, and a presidency with a popular mandate but limited coercive power. Pezeshkian campaigned on easing social controls, improving economic management, and reducing Iran’s isolation, yet his room to maneuver depends on accommodation with conservative power centers that still dominate parliament, the judiciary, and much of the security apparatus Reuters, July 6 2024 Carnegie Endowment for International Peace. That coalition dynamic matters because major policy disputes in Iran are usually settled not by formal cabinet hierarchy but by regime hierarchy: when the presidency clashes with the IRGC or institutions directly tied to the Supreme Leader, the presidency usually yields The Washington Institute Constitute Project: Constitution of Iran, 1989 revision.

Judicial independence is weak by design and weak in practice. The head of the judiciary is appointed by the Supreme Leader under Article 157 of the constitution, which binds the courts to the broader political order rather than insulating them from it Constitute Project: Constitution of Iran, 1989 revision. International human-rights reporting continues to document arbitrary detention, due-process violations, politically driven prosecutions, and the use of Revolutionary Courts in national-security cases, especially against dissidents, journalists, women’s-rights activists, ethnic minorities, and dual nationals UN Special Rapporteur on Iran, 2024 report Amnesty International: Iran 2023/24 Human Rights Watch: World Report 2025, Iran. The most serious rule-of-law concern remains the gap between constitutional form and enforcement reality: institutions exist, but in cases touching ideology, protest, or national security, courts function more as instruments of regime control than as neutral arbiters UN Special Rapporteur on Iran, 2024 report.

Reform efforts remain narrow,

Iran’s economy is large, state-shaped, and sanctions-distorted. The World Bank estimated nominal GDP at about $404 billion in 2023, with services the largest component, followed by industry, while agriculture remained a smaller share; the same source reports services at roughly half of GDP and industry at roughly a third in recent years World Bank Data – GDP (current US$), World Bank Data – Services, value added (% of GDP), World Bank Data – Industry, value added (% of GDP). Hydrocarbons still anchor the external account and fiscal system: Iran holds some of the world’s largest proved gas and oil reserves, and crude oil, petroleum products, and natural gas remain its main export earners despite sanctions pressure U.S. Energy Information Administration – Iran, OPEC Annual Statistical Bulletin 2024. Manufacturing is real but uneven; the IMF describes growth as supported by oil output and services, while sanctions, financing constraints, and governance problems continue to weigh on productivity and private investment IMF, Islamic Republic of Iran: 2024 Article IV Consultation.

Trade is concentrated in a narrow set of partners and channels that can absorb sanctions risk. Iran’s customs authorities reported China, Iraq, the United Arab Emirates, Turkey, and India among its principal trade counterparts, with China the leading destination for Iranian exports and the UAE a major hub for re-exports and payments Islamic Republic of Iran Customs Administration, IMF, Islamic Republic of Iran: 2024 Article IV Consultation. That pattern matters politically: Iraq provides a nearby market for gas, electricity, and manufactured goods, while China offers demand for discounted oil and a strategic buyer less responsive to U.S. pressure than European markets U.S. Energy Information Administration – Iran, IMF, Direction of Trade Statistics. The result is resilience, but of a specific kind: Iran can keep trading, yet often at lower margins, through intermediated logistics, and with higher transaction costs than peers that retain normal banking access World Bank, Iran Economic Monitor, IMF, Islamic Republic of Iran: 2024 Article IV Consultation.

The currency is a chronic pressure point and a direct policy constraint. The IMF’s 2024 Article IV reports inflation above 30 percent and identifies exchange-rate depreciation, monetized imbalances, and sanctions-related external frictions as key drivers of macroeconomic instability IMF, Islamic Republic of Iran: 2024 Article IV Consultation. Iran operates with multiple exchange-rate practices and a large gap between official and market rates, which creates rent-seeking opportunities and weakens policy credibility IMF, Islamic Republic of Iran: 2024 Article IV Consultation. The Central Bank of Iran and the Statistical Center of Iran both show persistent consumer-price pressure in recent years, and that feeds directly into household discontent because imported inputs, food, and housing costs reprice quickly when the rial falls Central Bank of the Islamic Republic of Iran, Statistical Center of Iran. For foreign policy, this means Tehran has a structural incentive to secure hard-currency inflows, protect oil exports, and avoid crises that trigger another sharp exchange-rate break unless a higher-tier security interest overrides the economic cost.

Fiscal policy is tighter than Iran’s welfare and subsidy commitments suggest because oil revenue is volatile and sanctions limit collection, borrowing, and repatriation. The IMF assessed the general government balance as remaining under pressure from large energy subsidies, pension obligations, and quasi-fiscal activity, even as higher oil production improved headline growth and revenue in 2023–24 IMF, Islamic Republic of Iran: 2024 Article IV Consultation. One major strength is redundancy: domestic industrial capacity, a large internal market, and diversified regional trade links make Iran harder to coerce than smaller oil exporters World Bank Data – Population, total, World Bank, Iran Economic Monitor. The main vulnerability is external-financial isolation combined with inflation. Iran can sell oil and survive sanctions, but it struggles to convert export earnings into stable growth, low inflation, and predictable imports; that gap is why Tehran often accepts tactical economic deals, especially with China, Gulf intermediaries, or neighboring states, without conceding on core security issues IMF, Islamic Republic of Iran: 2024 Article IV Consultation [blocked]

Iran’s security posture is built around deterrence by dispersion, missiles, proxies, and nuclear latency rather than formal alliance guarantees. The state’s military structure is dual-track: the regular armed forces (Artesh) handle conventional territorial defense, while the Islamic Revolutionary Guard Corps controls strategic missile forces, much of Iran’s expeditionary activity, and key internal-security functions; the Supreme Leader, not the president, is commander-in-chief under Article 110 of the constitution, which makes security policy ultimately a leader-centered file rather than a cabinet one Constitute Project, Constitution of Iran U.S. Institute of Peace, Iran Primer: The Revolutionary Guards. The International Institute for Strategic Studies assessed Iran’s active military personnel at roughly 610,000 in 2024, including about 350,000 in the Artesh, around 190,000 in the IRGC, and large reserve and paramilitary Basij components, making it one of the largest force structures in the Middle East IISS Military Balance 2024. SIPRI estimates Iran’s military expenditure at $10.3 billion in 2023 in current dollars, about 2.1 percent of GDP, a modest budget by regional standards but one directed toward missiles, drones, air defense, naval harassment capability in the Gulf, and partner forces abroad rather than expensive power-projection platforms SIPRI Military Expenditure Database Defense Intelligence Agency, Iran Military Power.

Iran has no NATO-style mutual-defense treaty system; its security network is political and operational rather than legal. Tehran’s closest military partners are non-state and quasi-state actors it arms, trains, or funds, including Hezbollah in Lebanon and aligned militias in Iraq and Syria, while its state relationships with Russia and China are strategically important but stop short of binding defense commitments U.S. Department of State, Country Reports on Terrorism 2023: Iran Congressional Research Service, Iran’s Foreign and Defense Policies. Iran became a full member of the Shanghai Cooperation Organisation in 2023, but the SCO is not a collective-defense bloc and offers Tehran diplomatic cover more than hard security guarantees Shanghai Cooperation Organisation Council on Foreign Relations, What Is the Shanghai Cooperation Organization?. In practice, Iran’s alliance behavior is most visible in the “Axis of Resistance”: support for the Assad government in Syria, Iraqi Popular Mobilization factions, Hezbollah, and the Houthis, giving Tehran forward pressure against Israel, the United States, and Gulf adversaries while preserving deniability International Crisis Group, Iran’s Hard View on Israel and the War in Gaza CSIS, Iran and the Axis of Resistance.

Iran’s active security environment is therefore regional and continuous even when it is not in declared interstate war. It faces low-level insurgent and militant threats on its borders, especially from Sunni extremist and Baluch separatist groups in Sistan and Baluchestan, and it has repeatedly exchanged fire across the Pakistan border after attacks claimed by Jaish al-Adl; it also treats Israeli covert action, U.S. military presence in the Gulf, and potential strikes on its nuclear infrastructure as first-order threats to regime security Reuters, Iran says strikes in Pakistan targeted anti-Iran militant group Jaish al-Adl International Crisis Group, Iran’s Security Policy in the Middle East. Iran’s naval posture in the Strait of Hormuz and Gulf is calibrated to hold shipping and U.S. assets at risk through mines, fast attack craft, anti-ship missiles, and drones rather than sea control in the conventional sense Defense Intelligence Agency, Iran Military Power. This posture reflects an interests hierarchy in which survival and regime security outrank economic normalization: Tehran accepts sanctions and diplomatic isolation more readily than it accepts military vulnerability or constraints on the IRGC’s regional tools Congressional Research Service, Iran’s Foreign and Defense Policies.

The nuclear file remains the central arms-control issue. Iran is a party to the Nuclear Non-Proliferation Treaty and continues to insist that it does not seek nuclear weapons, but the IAEA has reported uranium enrichment up to 60 percent purity and reduced transparency after the collapse of the 2015 Joint Comprehensive Plan of Action’s implementation pathway, leaving Iran with a short technical distance to weapons-grade material even though weaponization itself has not been publicly established by the IAEA IAEA, Verification and monitoring in the Islamic Republic of Iran in light of United Nations Security Council resolution 2231 United Nations Security Council Resolution 2231. Tehran’s negotiating position has been consistent on two points: sanctions relief must be concrete and verifiable, and any arrangement must preserve what it describes as its right to peaceful enrichment under the NPT; at the same time, its actual behavior since 2019 has been to expand enrichment and limit monitoring in response to pressure, which shows that coercion alone has produced escalation rather than disarmament Arms Control Association, The Joint Comprehensive Plan of Action at a Glance IAEA, Iran. The non-obvious point for delegates is that Iran’s security doctrine does not require

Iran is a young-but-aging, highly urban society whose politics are shaped by a gap between a centralized Islamic state and a diverse, educated population. Iran’s population reached about 89 million in the 2024 national census, with roughly 77 percent living in urban areas, and the median age is around the low 30s rather than the revolutionary-era youth bulge that defined the 1980s and 1990s Statistical Center of Iran, World Bank Data, UN Population Division. That shift matters politically: Iran still has large cohorts of young people, but it also faces slower population growth, lower fertility, housing pressure, and rising expectations from urban middle classes and graduates UN Population Division, World Bank Data.

Iran’s ethnic map is more mixed than the state’s Persian-centered national narrative suggests. The CIA World Factbook estimates Persians at a slight majority, with large Azerbaijani, Kurdish, Lur, Arab, بلوچ/Baluch, Turkmen, and other communities concentrated in distinct border and provincial zones CIA World Factbook - Iran. Persian is the official language, but Azerbaijani Turkic, Kurdish, Arabic, Balochi, Gilaki, Mazanderani, Luri, and Turkmen are widely spoken in daily life, and Article 15 of Iran’s constitution explicitly permits the use of regional and tribal languages in the press and schools alongside Persian, even though implementation has been uneven in practice Constitute Project - Constitution of Iran, Encyclopaedia Iranica. Religion is the regime’s main source of legitimacy: the constitution defines Twelver Ja‘fari Shi‘ism as the official religion, while recognizing Zoroastrians, Jews, and Christians as protected minorities Constitute Project - Constitution of Iran. The state has long treated the Baha’i community as outside that protected framework, and UN human rights reporting continues to document discrimination against Baha’is as well as pressure on some Sunni, Kurdish, and Baluch communities UN Special Rapporteur on Iran, USCIRF Iran.

Iran’s social profile combines strong human-capital indicators with heavy political constraint. Adult literacy is above 85 percent and youth literacy is substantially higher, while tertiary education expanded sharply after the revolution, including for women, who now make up a large share of university students in many fields UNESCO Institute for Statistics, World Bank Data. Life expectancy is in the mid-70s, and Iran built broad primary healthcare coverage through rural health houses and national vaccination programs, producing health outcomes well above many states at similar income levels World Health Organization - Iran, World Bank Data. But sanctions, inflation, brain drain, and shortages in imported medicines and medical inputs have put real stress on households and the health system alike World Health Organization - Iran, World Bank Iran Overview.

The main social tensions in Iran are not simply secular versus religious. They run across class, center-periphery inequality, gender, and the state’s coercive enforcement of ideological conformity. Protest cycles since 2017 have drawn in urban workers, students, women, and marginalized ethnic regions for different but overlapping reasons: inflation and unemployment in some places, demands for personal freedom and women’s autonomy in others, and long-standing resentment over discrimination and underdevelopment in Kurdish, Arab, and Baluch areas Carnegie Endowment for International Peace, Amnesty International - Iran, UN Special Rapporteur on Iran. At the same time, Iran retains real sources of social solidarity: a strong sense of statehood, dense family networks, Shi‘a commemorative culture, wartime memory from the Iran-Iraq War, and pride in national sovereignty all give the system resilience even when trust in officials is low Brookings Institution, Iran Constitution. That combination explains a core feature of domestic politics: society is fragmented enough to produce recurring unrest, but cohesive enough that opposition to the state does not automatically translate into agreement on what should replace it Carnegie Endowment for International Peace, International Crisis Group - Iran.

Iran treats climate policy as subordinate to energy security, sanctions resilience, and food-water stability, not as a standalone foreign-policy pillar. The country is highly exposed to heat, drought, desertification, dust storms, floods, and chronic water stress; the World Bank identifies Iran as one of the Middle East states facing worsening temperatures and declining water availability under climate change, while the UN Development Programme and Iranian official reporting have linked repeated drought and land degradation to internal displacement, agricultural losses, and public-health stress World Bank Climate Change Knowledge Portal – Iran UNDP Iran – Environment and Climate Change. Iran’s Department of Environment has also warned of severe wetland loss and dust-storm exposure tied to both climate shifts and mismanaged water use, especially around Lake Urmia and the Mesopotamian dust corridor Department of Environment of the Islamic Republic of Iran. In practice, Tehran frames environmental risk through survival and regime-security lenses: water scarcity, crop losses, and pollution matter because they can trigger protests, migration, and infrastructure strain more quickly than they alter Iran’s multilateral image UNDP Iran – Environment and Climate Change World Bank Climate Change Knowledge Portal – Iran.

Iran’s energy mix remains overwhelmingly hydrocarbon-based despite official support for renewables. The International Energy Agency reports that Iran’s total energy supply is dominated by natural gas and oil, with gas central to power generation and household consumption, while hydropower, nuclear, solar, and wind remain much smaller contributors IEA – Iran. Electricity generation data from the IEA likewise shows fossil fuels supplying the vast majority of output, which helps explain why emissions policy is constrained by subsidy politics, domestic demand growth, and export strategy IEA – Iran. Iran is a party to the Paris Agreement, and its nationally determined contribution submitted to the UNFCCC offers a 4% reduction in greenhouse-gas emissions relative to a business-as-usual pathway unconditionally and up to 12% conditionally, explicitly tying stronger action to sanctions relief, finance, and technology transfer UNFCCC NDC Registry – Islamic Republic of Iran. That conditional structure is the key to Iran’s climate diplomacy: Tehran supports climate equity language and common-but-differentiated responsibilities, but it presents sanctions as a direct obstacle to mitigation investment and cleaner technology access UNFCCC NDC Registry – Islamic Republic of Iran.

Iran does have a legal and institutional environmental framework, but enforcement is uneven and often loses to industrial, agricultural, and security priorities. The Department of Environment is the core civilian regulator, and Iran’s Environmental Protection and Enhancement Act provides the basic statutory foundation for pollution control and habitat protection, while the Clean Air Act of 2017 created a more specific framework for emissions, fuel quality, and urban air-pollution enforcement Iran Department of Environment – Laws and Regulations FAO FAOLEX – Clean Air Act of the Islamic Republic of Iran. Iran is also a party to major environmental treaties including the UN Framework Convention on Climate Change, the Paris Agreement, the Convention on Biological Diversity, and the Ramsar Convention, which matters because Iranian diplomacy often uses treaty participation to show that the state is not rejecting environmental governance outright UN Treaty Collection – Paris Agreement Ramsar Convention – Iran country profile. The gap is implementation: the OECD has noted that fossil-fuel subsidies and weak pricing signals distort energy use across the region, and Iran’s own air-quality and water-management problems show how hard it is to turn legal mandates into compliance under sanctions and fiscal pressure OECD – Fossil Fuel Support and Climate IEA – Iran.

The sharpest active disputes are over water, ecosystems, and pollution rather than formal interstate climate negotiations. Iran has repeatedly clashed with Afghanistan over Helmand River flows affecting Sistan and Baluchestan, with Tehran citing treaty rights and accusing Kabul of failing to release sufficient water, while Afghan authorities point to drought and infrastructure constraints; this is one of the clearest cases where environmental stress spills into security rhetoric Reuters Iran Ministry of Foreign Affairs. Iraq and Iran also share responsibility for dust storms and wetland degradation in the border region, where drainage, damming, and drought have intensified transboundary environmental damage UNEP – Sand and Dust Storms in West Asia. Inside Iran, deforestation in the Hyrcanian forests, wetland shrinkage, over-extraction of groundwater, fisheries pressure in the Caspian and Persian Gulf, and some of the world’s worst urban air pollution remain persistent disputes between conservation bodies, local communities, and development ministries FAO – Global Forest Resources Assessment, Iran UNDP Iran – Environment and Climate Change. The non-obvious point is that Iran’s climate posture is not climate-minimal because officials deny the problem; it is climate-limited because the state sees environmental action through the hierarchy of sanctions survival, energy access, and domestic order first, and through emissions diplomacy second UNFCCC NDC Registry – Islamic Republic of Iran IEA – Iran.

Iran’s most important development in the last 90 days is the return of direct military confrontation with the United States around the Gulf file, alongside a parallel diplomatic track that neither side has fully closed. Reuters reported on 10 June that U.S. and Iranian forces exchanged strikes after a period of escalating attacks tied to regional maritime and military targets, pushing the crisis beyond proxy competition into overt state-to-state action Reuters. On the same day, Reuters and other major outlets also reported movement toward a U.S.-Iran “peace memorandum,” indicating that even after the strikes, both governments were still testing a limited de-escalation channel rather than committing to open-ended war Reuters. That combination matters more than the battlefield details alone: Tehran is signaling that it will absorb risk to defend deterrence and regional access, but it is also leaving room for a negotiated pause if core security and regime-survival interests are protected Reuters.

The second major development is the reactivation of the nuclear-pressure track at the IAEA. On 10 June, diplomats told Reuters that the IAEA Board of Governors was drafting a resolution on Iranian inspections, reviving a familiar pattern in which technical safeguards disputes become the entry point for broader political coercion by the United States and European states Reuters. That comes at a moment when President Masoud Pezeshkian’s government still lacks freedom to make a strategic nuclear concession without buy-in from Supreme Leader Ali Khamenei and the security establishment, which means the real decision structure remains centered above the presidency Encyclopaedia Britannica, Reuters. In practice, Tehran’s likely response is dual-track: public defiance on sovereignty and inspections, coupled with selective tactical cooperation if it can slow a UN or Western escalation cycle without appearing to yield under fire IAEA, Reuters.

The development to watch next quarter is whether the emerging IAEA resolution and the reported U.S.-Iran de-escalation channel collide or reinforce each other. If the Board adopts a harder line and Iran answers by cutting inspector access or expanding sensitive nuclear activity, the Gulf military crisis and the nuclear file will merge into one escalation ladder; if back-channel diplomacy produces even a narrow understanding on strikes, shipping, or inspection modalities, Tehran may try to compartmentalize the two fronts and avoid a broader war IAEA, Reuters.
