None of the recently attacked countries posed an imminent threat to the US.
In what kind of deranged world are we living that people are fighting against the notion that waging war on another country should be a costly decision!?
My, the Overton window has indeed shifted far.
Yes, it is prudent to destroy the nuclear capability of a country that chants "Death to America" before they become an imminent threat.
Had the US waited until Iran were an eminent threat and then suffered a nuclear blast in one of her harbours, they would have nothing but "I told you so" to comfort them. Don't let your repulsion of war blind you to the fact that other cultures with different values don't have the same repulsion as you.
