I would nuke my top 2 enemies, and sort out the damage later on.
That would be iran and n. korea, imho
It's not like after we've got 20 of our cities in flames, that anyone's going to CARE about world opinion.
But then would Russia and China say...Here is our justification(to do what they want to do anyways) and then start sending the missles.
You forgot France.
The way I see it...The big threat countries have not been a real problem because of the threat of mutual self destruct. But when you have people runing down main street carring WMD and you don't even know who to blame if one is used...because there are so many people it could be...From a strategic point of veiw...Mutual self destruction becomes a bit meaningless.
We either knock of the PC stuff and secure our country from within of else we are going to suffer the consequences of our enemies. We made it quite easy for them by giving up our nationalism.
