Is this for real? Is President Bush or anyone else in a position of power truly, seriously thinking about dropping nuclear bombs on a country that poses no direct threat to the United States, possesses no nuclear weapons of its own, and isn't likely to for at least a few years? Pre-emptive war-attacking a country to keep it from attacking us or an ally-is sometimes justifiable. Preventive war-attacking a country to keep it from developing a capability to attack an ally sometime in the future-almost never is. And preventive war waged with nuclear weapons is (not to put too fine a spin on it) crazy.
