The Treaty on Prohibition of Nuclear Weapons has not succeeded in adding any additional universal stigma to nuclear weapons. It lacks the support base needed for replacing the Cold War vintage “Mutual Assured Destruction” with “Mutual Assured Abstinence”. The nuclear weapon countries’ faith in the deterrence logic remains intact.

The standoffs in Doklam and North Korea offer insights on how crisis stability remains subject to the complexities of deterrence, especially in theatres with multiple nuclear-armed states, and what this entails for disarmament.

While thermonuclear weapons are not necessary for maintaining a credible deterrent, they serve the purpose of enabling India to make effective use of its relatively limited fissile material stockpile.

The nuclear escalation risk cannot be contained by the revision of India’s minimum deterrence policy but with a change in Pakistan’s behaviour.

There will be little legitimacy for a pre-emptive US strike on North Korea unless Pyongyang launches a pre-meditated strike on any nation.
