Specifically why do you think that? What in the response to 9-11 makes you think the USA would go nuclear on some nation's arse? There would be a response, but no nukes.
That's not naive nor stupid.
The USA isn't nuking anybody in that context, anytime.
Boy are you wrong! You are just hoping we would not, but we would massively. The American people will stand up and cheer. Yes the majority of American's would demand it. The majority would cheer when Damascus, Tehran, and other places ceased to exist overnight. Israel would respond as well with her own submarines and nuclear tipped cruise missiles as well as Jericho missiles in hardened silos. The President does not need permission and just like 911 the whole country including the delusional media would be calling for blood. Even Dan Blather was crying after 911 and acting like a panicked little girl wetting her pants the day after 911 and kept it up until he fealt is was safe to be a liberal pansie again after no more hits occured on U.S. soil. Americans ae sick of terrorists, radical muslims, sick of Iran, and sick of the last three decades of letting these little sh*ts jab at the Untited States with their murderous little terrorists and than claim they can't be held responsible. Well, when they set off a nuke anywhere all bets are off and they are to late to say it was not their fault.
