Mind Blowing - and Land Blowing Concept

     Eli has put up the basic history of the nuclear bombs, so I do not feel it is necessary to dive into it. I would like to say that the purpose of nuclear weapons is pointless, because they were made to obliterate a nation as a last resort. However, this would mean that the other nation would also fire off its nuclear warheads, causing utter destruction. I understand that in the past, the bombs were made to end a war, and they served the purpose effectively. However, the atomic bombs dropped on Hiroshima and Nagasaki were at a primitive stage, but were still effective forms of destruction. It is unnecessary for anything of greater destructive power. Obviously there are are a few exceptions such as the anti-meteor nuclear warhead prepared for a cosmic threat, but other than that, the extra firepower is just overkill. Nuclear weapons are the most dangerous things that humans have invented, but we are making it worse and worse.  An eye for an eye leaves everyone blind, but a head for a head leaves everyone dead.
