Well, I’d say stopping immigrants and visitors from those countries, coupled with Israeli-style flight security measures, would have stopped another 9/11.
So, no, I don’t see any evidence that our trillions and our thousands dead bought anything over what I mention above.
You seem to think the trillions and deaths were a bargain.
Pretty sick of you.
Post #28 nailed it! Immediately after 9/11, all immigration, refugees, and visitors from all Muslim and African nations should have been suspended.
