But McCain would go to war over ownership of a cow turd.
He wants to remove Assad. Okay, that means allying with ISIS...and taking sides against Russia (and Iran).
How can you possibly win in such an equation?
I didn't follow McCain's political career very closely until he ran for President in the 2000 primaries, but from what little I recall he started out as a relatively sensible, realist voice of reason on foreign policy. In the late 1990's, he fell under the wing of the neoconservatives, and has been parroting Bill Kristol's foreign policy talking points ever since.
That accounts for his obsession with Assad - for PNAC, removing Assad and other secular dictators is a higher priority than fighting actual Islamist terrorists.
Don’t mind McCain, he’s becoming senile.
As an Iowan I can say, it's a pie. ;-)
