Everybody's first reaction is conventional warfare. All that does is cause what we are in in Iraq right now. If Iran wants to have nukes, we should supply them with some in Tehran and Natanz. They think we don't have the will to stand up to them is why we are having these problems now. I feel sorry for the people that don't support the regime, but why do we have to wait for a mushroom cloud here before we get "real mad".
Prevailing winds and geography would ensure that any nukes used against the NK forces would also end up destroying Seoul - either through blast effects or through fallout/radiaton. Do you think that killing millions of our ally’s citizens is a good idea?????
