Essential Reading on the Probability of Nuclear War

Unfortunately, it seems that humanity is locked into the occurrence of a nuclear event. The world minus nuclear weapons is the Second World War, which is also unacceptable and the probability of a nuclear event in any given year, though tiny, approaches 100 percent over a unknown number of years (depending on the original values per year, which of course, can never be anything more than estimates).

Perhaps the only answer to this is that if we have nothing to lose, we should work for peace.  

Today I discovered the blog of Martin Hellman, a former electrical engineering professor at Stanford University. He has apparently dedicated several decades to calculating the risk of a nuclear war. His blog makes for important reading.
