No group in the middle east should ever trust the US. We abandoned the Iraqi rebels after the gulf war and Saddam butchered them. We abandoned the democratic govts in Afghanistan and Iraq and now they are fodder. We abandoned the democratic movement in Iraq and now the Syrian moderates. Not to mention Israel and the Christian community. The US is bad news unless you want to move there as a refugee.
Because one never knows who the next president will be. The Russkies don’t have that problem.
