Within the Obama administration, probably up to the Preisdent himself, there are many leftists who WANT Iran to get a nuclear weapon.
Except that I would change it to "leftists and Muslim sympathizers." I don't know if Limbert is actually a Muslim (although if he was actually out there shouting the Allah thing, it sounds pretty likely), but if he isn't, he's certainly a sympathizer, and they're just as bad.
I might give him a pass on that. If I managed to escape the Embassy I'd try to blend in while working my way to the edge of the crowd, and ultimately the Canadian Embassy.
I say might, because from the reportage, it's by no means clear that was the case.
(BTW, Canada? Thanks again for your kind assistance in those dark days)
