They keep asking for 'the bomb' whilst making warlike noise and lobbing their 'stolen or gifted' rocket technologies over the Pacific in our general direction. Just because the North has a favorite status with some in China, they get to be paranoid on a terrorist level & get away with it.

Why can't we gift them a few 'neutron versions' that won't irradiate South Korea, China, or Japan?
The launch, targeting, & fusion ignition devices - would not need to be included with delivery. ;)
