Why america if free to store, construct, test any atomic weapons, nuclear reactors but other countries aren't?:
Is this a question, or a US bashing, I'm not sure. I often ask myself that same question though. The most honest answer might be because we can control our technology, and we have the power to control proliferation too because we see it as a danger. In general, it's probobly not a good idea for every Tom, Dick, and Harry to have Atom bombs. Do you really think nothing bad would happen if every country had enough bombs to destroy the planet? Yea that would be swell. 

I do have to admit there is a certain irony to the United States being so controling about nukes. We say we can't trust others to have them, but who's the ONLY county crazy enough in the history of the world to actually use one... Yep.
