Is nuclear war survivable? Only predictions exist, as some say yes, others say no. Keep in mind that modern thermonuclear weapons are many hundreds, and in the case of the largest weapons, several thousand times more powerful than the bombs dropped on Hiroshima and Nagasaki in 1945. We really do not fully understand what will happen when thousands of these weapons are detonated at the same time. For some, especially those in large population centers, it may seem like an entirely futile endeavor. If it is survived at all, it will be by those who are mentally and logistically prepared for such an event and that live in very remote areas with no strategic significance.
