Nuclear Arms Control Faces Challenges in 2026
In 2026, two important events will happen that could make it harder to control nuclear weapons.
First, an agreement between the US and Russia called New START will expire, and there's no new agreement to replace it.
This means there won't be as many rules or inspections to limit nuclear weapons.
Second, a meeting called the NPT Review Conference will happen in New York, but experts think the countries won't agree on anything new.
Some people are worried that without these agreements, it will be harder to prevent nuclear conflicts.
China is also building more nuclear weapons, which makes things even more complicated.
While some people think the US shouldn't make new agreements with Russia, others worry that without them, the world will be less safe.
The New START treaty between the US and Russia is set to expire on February 5, 2026, with no clear replacement in sight.
The NPT Review Conference in April 2026 is expected to fail to produce a final agreement, similar to the last two sessions.
Experts warn that the global nuclear arms control architecture is 'crumbling', with increasing tensions and technological advancements complicating deterrence.
China's rapid nuclear buildup and refusal to engage in trilateral disarmament talks add to the challenges.
While some argue that allowing New START to lapse is in the US's interest, others warn of the risks of reduced safeguards and diplomatic tools.
