@SW-User 'did they shoot down a commercial plane with innocent civilians?'
No it was the good ol' US of A that did that back in '88 ;
"Iran Air Flight 655 was a scheduled passenger flight from Tehran to Dubai, via Bandar Abbas, that was shot down on 3 July 1988 by an SM-2MR surface-to-air missile fired from USS Vincennes, a guided missile cruiser of the United States Navy. The aircraft, an Airbus A300, was destroyed, and all 290 people on board, including 66 children, were killed.[1] The jet was hit while flying over Iran's territorial waters in the Persian Gulf." - wiki
