Nuclear Proliferation is inevitable.
When the first of our ancient predecessors picked up a tool and beat his cousin to death with it we were doomed to have an arms race. As one tribe (clan) used how to use bronze, silver, gold, steam, petroleum, nuclear, silicon, etc, etc, the neighboring clans were forced to keep up either by hacking the original or by taking it to higher level.
Unfortunately, Mans greatest accomplishment seems to be in the efficeincy that we can kill our fellow beings. That sucks!
