The Cold War ended 20 years ago, but I still wonder: is nuclear war still a danger to mankind? How likely is it that we'll experience a nuclear war in, say, the next 20 years? I mean, it seems like there are a lot of situations that can quickly get out of hand and lead to one. 1.) A war in Iran 2.) Georgia joins NATO then gets invaded by Russia 3.) A war with China 4.) India-Pakistan 5.) An end-times fundamentalist like Michele Bachmann or Sarah Palin gets his/her hands on a nuclear arsenal. Am I just being paranoid or are these valid concerns?
