Yeah. To me, this is one of the real foreign affairs issues over which we have some very, very difficult choices.
The very simple truth is this - nuclear weapons are straightfoward (physics, engineering). They just take money. Any nation with the money to spend can develop them, if they so choose.
There seems to be no end of people who think that Obama can stop Iran from getting nuclear weapons, but I think the opposite is what history shows us.
The US, any given President, is not able to stop a nation to get nuclear weapons if they really want them.
