Iran and the militia behind this will get their asses kicked. Don't worry about that.
Several thousand “protestors” breeched the outer wall of our embassy. They torched a guard tower and reception area (there are pictures of this on the Internet).

Rubber bullets are a joke to people who only respect strength and power. We had better bring the hammer down or Iran quick.
