The strong focus on this one state, however, is also a timely moment to note that a number of relatively small states in broadly similar circumstances of insecurity have also had nuclear ambitions. These states are commonly described by analysts of international security as “fortress” or “garrison” states. How their nuclear stories worked out is worth recalling in today's dangerous atmosphere, particularly with Trump in the White House.
The main contenders in this group are Taiwan, South Korea, South Africa, Israel and North Korea itself. It's true that several other states have had nuclear intentions, and took at least initial steps. Argentina and Brazil, and (perhaps surprisingly) Switzerland and Sweden were among them, but all terminated their programmes at quite an early stage. Of the five fortress states, two have not gone the whole way, one did so and then gave them up, one has a large and powerful nuclear arsenal and one – North Korea – is almost there.
What of the other four?
