Too right. It was a mistake in my view too. But think Saudi Arabia and our oil interests; SA likes the Americans to do the dirty work for them. Don’t the Saudis have a military of their own? Can’t they do anything to defend themselves except to fund and spread radical Islam (aka ISIS) now, along with their satellites in the Gulf? Qatar comes to mind too.
