Quote from Nick Leeson Jr:
I have complete faith that if the US was ever attacked with, say one nuke, where the origin of the nuke was not completely clear, or if any ambiguity existed, the US would simply and quietly bow to UN pressure to "show restraint", and probably nothing would happen; other than a few European papers printing "we are all Americans now", the hogs & pigs of the Muslim world praising Allah, and the American Universities having teach-ins on why we(the nation) deserved it.
Even if the origin of the nuke was known, and there was a nuclear exchange, it would be limited on the part of the US.
IF it was a missle we would know where it came from after about 15 minutes after takeoff probably sooner.
Wherever it came from would cease to exist shortly after.
