They're all Muslims, aren't they?

Sunnis? Shiites? Whatever.

According to The Raw Story, Peter Galbraith, former U.S. ambassador to Croatia, claims in a new book that "President George W. Bush was unaware that there were two major sects of Islam just two months before the President ordered troops to invade Iraq".

More: "In his new book, The End of Iraq: How American Incompetence Created A War Without End, Galbraith, the son of the late economist John Kenneth Galbraith, claims that American leadership knew very little about the nature of Iraqi society and the problems it would face after the overthrow of Saddam Hussein."

But we knew that already, didn't we? It'd be funny if it weren't such a nightmare.
