Is it really prudence to attack Middle Eastern states to stop them from getting the bomb? To trade guaranteed lives lost for possible lives lost? If we could wave a magic want and keep Iran from ever getting nukes, I would advise it. However, we don't have any magic wands, all we have is human means, and they all involve trade-offs. If we want to keep nukes out of the hands of a state determined to get them, there's no way it doesn't cost us dearly.
I'm not anti-Christian. I'm anti-stupid.
