Comprehensive disarmament refers to arms-control efforts that address weapons systems as an interconnected whole, aiming for deep, verifiable reductions across nuclear, biological, chemical, and conventional categories, often alongside limits on delivery systems and military expenditures. It is typically contrasted with partial or sectoral disarmament, which targets a single weapon class (for example, a ban on landmines or cluster munitions).
The concept has deep roots in the United Nations system. The first resolution adopted by the UN General Assembly, Resolution 1(I) of 24 January 1946, called for proposals to eliminate atomic weapons and other weapons of mass destruction. The phrase "general and complete disarmament under effective international control" was later embedded in Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT, 1968), which obliges parties to pursue negotiations in good faith toward that end. The UN's first Special Session on Disarmament (SSOD-I) in 1978 produced a Final Document that remains a reference point for comprehensive approaches.
In practice, comprehensive disarmament has proven elusive. Cold War-era Soviet and U.S. proposals for "general and complete disarmament" in the early 1960s (notably the 1961 McCloy–Zorin Accords) set out shared principles but produced no binding regime. Subsequent progress has been incremental and sectoral: the Biological Weapons Convention (1972), the Chemical Weapons Convention (1993), bilateral nuclear treaties such as START and New START, and the Treaty on the Prohibition of Nuclear Weapons (2017).
Key debates concern:
- Verification: how to monitor reductions across multiple weapon types without compromising sovereignty.
- Sequencing: whether nuclear-weapon states must lead, or whether parallel conventional cuts are required.
- Linkage: whether disarmament should be tied to broader security guarantees, dispute-settlement mechanisms, or development financing.
For Model UN delegates, comprehensive disarmament is most often debated in the First Committee (DISEC) and the Conference on Disarmament in Geneva.
Example
At the 2018 UN General Assembly, Secretary-General António Guterres launched his "Securing Our Common Future" agenda for disarmament, calling for comprehensive action across weapons of mass destruction, conventional arms, and emerging military technologies.
Frequently asked questions
Arms control regulates and limits weapons (numbers, deployment, testing) without necessarily eliminating them. Comprehensive disarmament aims for actual reduction or abolition across multiple weapon categories.
