You bring up a great point I never thought we’d have to consider - If there is a nuclear weapons confrontation between the United States and North Korea, apart from the millions of people who would die in the initial blasts, what would the world wide collateral damage be from radioactive fallout? - And how would the other nations of the world respond? - The world community ISN'T going to say, "Good going Trump, you sure showed him. That Rocket Man guy was asking for it. It was all his fault. And we don’t mind eating cesium-137, strontium-90 & iodine-131 for generations."
