One point of fact guys, The Iranians have been fighting their war against us for years. Have we been fighting back? No. I don't see that we can laugh off their claims so easily.
Our lack of a response to these nimrods goes back to Reagan and every president since.
Going back to the Marine Barracks in Beriut to providing shape charges for IEDs in Iraq, they are killing US personnel and getting away with it. Our intel people have the goods on them. We have not forced them to pay any price for their activities.
Why should they stop?
I concur and believe they will do a great deal more damage to us because the President's hands have been tied by political enemies. I don't see preemptive action only a Pearl Harbor like response.
