> I don't want Trump to have the power to accidentally the whole world because he couldn't keep his short, fat fingers from a big red button he couldn't read the label for. I do not, however, believe their removal would positively affect world peace Therein lies the problem with nuclear weapons: they will never be used to win a world war by a calculating Hitler-like figure, but they can be used to kill most people on earth by an irrational Osama-like leader. And since democracy and most other political systems frequently promote irrational figures in positions of authority, nuclear weapons (or rather, large nuclear stockpiles) pose a fundamental new problem for humanity, with no precedent in the history of war: catastrophic negative externalities for political insanity. The consequences of wars are no longer limited to the belligerent parties, but exported thought the world to peaceful and neutral nations. It's therefore rational for anybody to seek world denuclearization. As a side comment, a good example or irrational behavior is the US treatment of Iran - a country that agreed not to proliferate only to be currently jerked around - versus the overtures made to North Korea after it obtained nuclear weapons. The political value of nuclear weapons becomes clear - although the reasons why US is pursuing this strategy of pushing states to proliferation is much less clear, and have to do with irrational internal US politics.
