No one here is Jewish, so it's cool.

How do you know they're terrorists? Are the kurds terrorists? Is anyone opposing Assad a terrorist? What does that make the Russian supplied rebels in ukraine?

The middle east is filled with bloodthirsty lunatics so it's always safe to assume that any middle easterner with access to weapons is a terrorist.

Taking sides in any middle eastern civil war is insane. Let them eat each other and hope the ones left standing will be rational enough to do business with us. They need our technology to efficiently extract the oil so the least they can do is cut us a deal.

Bearded guys with weapons

they're designed to hit a certain part of a tank, typically meaning they actually fly just above the tank and then setting off a downward facing shaped explosive. Or, they may travel up and then come down at an angle to hit the top of the turret or the intersection where the turret and chassis meet, where armor is weakest. All of that independent of the operator. So once locked on and fired, the launcher and missile work together to determine the best angle to hit the tank at.
