Why would they protest their allies?
It was never a “peace” movement or “anti-war”. it was simply anti-US/anti-Republican. They don’t even march against Obama’s wars in Libya, Afghanistan, and elsewhere.
Useful idiots on FaceBook are saying this is all Bush’s fault for invading Iraq. We deposed Saddam, we didn’t colonize it. They established an Islamic theocratic government, that isn’t a US construct.
