Analyse the barriers to arms control. (1998)
Arms control differs from disarmament. It does not abolish weapons. It is cooperation between adversaries to reduce the likelihood of war, its destructiveness if it comes, and the cost of preparing for it. Thomas C. Schelling and Morton H. Halperin (Strategy and Arms Control, 1961) and Hedley Bull (The Control of the Arms Race, 1961) set out this idea. Its barriers are structural, technical, domestic and normative, and they reinforce one another.
Structural barriers
- Anarchy and the security dilemma: without a sovereign above states, each fears cheating; John H. Herz and Robert Jervis showed how defensive measures look offensive to the rival.
- Relative gains: Joseph M. Grieco (1988) argued that states ask who gains more, not just whether both gain. A treaty that benefits both can still be rejected if it benefits the rival more.
- Asymmetry: forces differ in geography, doctrine and type, so equal ceilings rarely give equal security. Hans J. Morgenthau called this the problem of ratio.
- Multipolarity: Cold War arms control was bilateral. With China at about 620 warheads (SIPRI, 2026) and growing fastest, parity among three cannot be defined; Beijing rejects trilateral talks, and the China–India–Pakistan chain links every pair.
Technical barriers
- Verification: launchers can be counted, but warhead loadings, stockpiles and accuracy are hard to see, and intrusive inspection clashes with sovereignty. Washington’s 2026 charge of a concealed Chinese low-yield test, which Beijing denies, shows how unverifiable suspicion poisons talks.
- Technological change: MIRV multiplied warheads just as SALT I limited launchers. Hypersonic glide vehicles, dual-capable missiles, cyber tools and autonomous weapons today have no agreed definition or counting unit.
Domestic and institutional barriers
- Interests: Dwight D. Eisenhower’s military-industrial complex, service rivalries and the electoral fear of looking weak favour more buying.
- Ratification politics: the US Senate rejected the CTBT in 1999 (51–48): leaders can negotiate what legislatures will not approve.
- Exit and erosion: the ABM Treaty ended in 2002, the INF in 2019 and Open Skies from 2020. Russia de-ratified the CTBT in 2023, and New START expired on 5 February 2026 with no successor.
- Forum paralysis: the Conference on Disarmament works by consensus. It has concluded nothing since 1996, and Pakistan has blocked FMCT talks since 2009.
Normative and political barriers
- Perceived discrimination: regimes that freeze a hierarchy, like the NPT, are resisted by those left out; Jaswant Singh called it nuclear apartheid (1998), and India refused both the NPT and CTBT.
- Management, not reduction: Alva Myrdal (The Game of Disarmament, 1976) argued that superpower talks channelled the race rather than ending it, breeding cynicism among non-nuclear states.
- Linkage: arms control depends on the wider relationship. The Ukraine war led Russia to suspend its participation in New START in February 2023, and the 11th NPT Review Conference failed in May 2026 over Iran and Ukraine.
How the barriers interact
Distrust raises the demand for verification, which requires intrusion that sovereignty resists; technology outpaces whatever is verifiable, and domestic interests exploit the gap. Each barrier strengthens the others.
Conclusion
The barriers are mainly political, not technical. Bull argued that arms control works only when adversaries share an interest in avoiding war. Modest steps still succeed: the India–Pakistan agreement on not attacking nuclear installations (1988), with lists exchanged every 1 January, and the 2005 missile-test notification pact show that transparency is possible even between rivals.
