Model DiplomatMay 5, 20262 min readMiddle East [ReutersTrump: New deal with Iran will be better than old one | Reuters](https://www.reuters.com/world/trump-new-deal-with-iran-will-be-better-than-old-one-2026-04-20/)[Matt SpetalnickWith his promises of peace unmet in Gaza and Ukraine, Trump may find Iran just as tough | Reuters](https://www.reuters.com/world/with-his-promises-peace-unmet-gaza-ukraine-trump-may-find-iran-just-tough-2025-04-18/)[Francois MurphyWhat might a US-Iran nuclear deal entail?  | Reuters](http://today.reuters.com/world/middle-east/us-seeks-deal-prevent-iran-acquiring-nuclear-arsenal-2026-02-26/) ## Trump's Iran Deal Push Runs Into Obama's 2015 Baseline *Trump wants a tougher Iran deal, but Tehran's nuclear gains and Washington's own red lines leave little room to beat the JCPOA.* Trump is **trying to negotiate against the clock and against his own precedent**. France 24 reports that he is hard-pressed to secure a better Iran nuclear agreement than Barack Obama’s 2015 deal, because that accord already set the working baseline for enrichment caps, inspections, and sanctions relief. [France 24](https://www.france24.com/en/trump-fears-may-not-get-better-iran-nuclear-deal-than-obama-s "france24.com") The problem is that Trump pulled the U.S. out of the JCPOA in 2018, then inherited the consequences: Iran now has a much larger enrichment program than it did under Obama’s terms. [Reuters](https://www.reuters.com/world/middle-east/us-seeks-deal-prevent-iran-acquiring-nuclear-arsenal-2026-02-26/ "reuters.com") [Reuters](https://www.reuters.com/world/middle-east/iran-us-resume-talks-oman-narrow-gaps-over-new-nuclear-deal-2025-04-26/ "reuters.com") ## The leverage has shifted to Iran The 2015 JCPOA capped enrichment at 3.67%, restricted centrifuges, and opened Iran to expanded IAEA oversight; Reuters notes that after Trump quit the deal, Iran breached those limits and later moved up to 60% enrichment, close to weapons grade. [Reuters](https://www.reuters.com/business/energy/any-trump-deal-with-iran-must-tackle-nuclear-watchdogs-blind-spots-2025-06-03/ "reuters.com") [Reuters](https://www.reuters.com/world/middle-east/iran-s-stock-near-bomb-grade-uranium-grows-sharply-iaea-report-shows-2025-02-26/ "reuters.com") That matters because a nuclear deal is no longer about rolling Iran back to 2015 conditions; it is about freezing a far more advanced program before it becomes even harder to monitor. For the broader regional picture, see [Conflict](https://modeldiplomat.com/discover/conflict "modeldiplomat.com"). Iran’s bargaining power is straightforward: it can offer limited curbs and better access in exchange for sanctions relief, while keeping enough enrichment capacity to preserve a latent nuclear option. [Reuters](https://www.reuters.com/world/middle-east/iran-us-resume-talks-oman-narrow-gaps-over-new-nuclear-deal-2025-04-26/ "reuters.com") The United States still has pressure tools — sanctions, military signaling, and control over what relief it can credibly grant — but it cannot recreate the 2015 inspection architecture quickly, especially after years of lost IAEA continuity of knowledge. [Reuters](https://www.reuters.com/business/energy/any-trump-deal-with-iran-must-tackle-nuclear-watchdogs-blind-spots-2025-06-03/ "reuters.com") [Reuters](https://www.reuters.com/world/middle-east/iran-s-tangled-nuclear-dispute-with-west-2025-04-08/ "reuters.com") ## The real fight is over the endpoint The talks are colliding over two incompatible end states. Reuters says Secretary of State Marco Rubio has demanded that Iran stop enriching uranium entirely, while Iranian officials call enrichment and missile capabilities non-negotiable red lines. [Reuters](https://www.reuters.com/world/middle-east/iran-us-resume-talks-oman-narrow-gaps-over-new-nuclear-deal-2025-04-26/ "reuters.com") Israel is pushing an even harder line, urging a Libya-style dismantlement that Tehran is very unlikely to accept. [Reuters](https://www.reuters.com/world/middle-east/trump-wants-deal-with-iran-success-talks-unlikely-israeli-officials-say-2026-03-24/ "reuters.com") ## What to watch next The next decision point is whether Washington settles for an interim deal — a monitored enrichment cap, stockpile accounting, and stronger IAEA access — or keeps insisting on zero enrichment and risks talks collapsing. Reuters’ reporting suggests that a broad bargain is still technically possible, but only if Trump accepts that a “better” deal may mean tighter verification, not a more maximal rollback.
