Sorry m8 I misunderstood you..
I believe you are mistaken that Bush and Co would NOT use tactical nukes, at least the "bunker buster" types on Iran.
I thought you were talking about Real Nukes..you know..missles-a-flying, mushroom clouds filling the landscape.
bunker busters..yea I can see that. Minimal Eradiated areas.
Lets say for argument that a Nuke went off in L.A. and we "found" it to be "Iran" that did it..
I still dont see us Nuking the hell out of any nation, for whatever reason, unless its an all out WW III. Just my opinion ..
