Failed? It was a spectacular success. They spent $$ Pedo Joe gave them. Made Israel, the US and a few others waste more $$ shooting down or pretending to shoot down something all so the can rail on about their tremendous attack on the Jewish enemy. Good PR for the Mullahs especially when the Great Satan foots the bill.

Someone I heard yesterday interpreted this as a successful plan to have a limited attack from Iran which will show up all the strengths and weaknesses of the defense systems as well as the locations of Israeli military defense coordination points. Today’s version of exposing the flak sites in earlier wars. Iran and others used up Israeli weapons and learned a lot to instruct other enemies of Israel.
And one Israeli airfield is out of commission now.
