Using a single one preemptively on a country that poses zero threat to us as a country is a holocaust. It's also stupid and insane. And yes, I would call anyone who is proposing that stupid and insane to their face, including my commander in chief, the SMA, and of the JCS, the NSA or the SecDef.
Correct, precisely why it ain't gonna happen.
All this blather is nothing more than braggadocio between two ego maniacs.
