Did Iran sanction the action? What were we doing there in the first place?So since Al Quds soldiers have been captured in Afghanistan fighting with the Talib against U.S. forces we would be justified in attacking Iran?
The law doesn't permit an aggressor to claim self defense when he started the fight in the first place. It's also fallacious to claim a right to attack a nation because a few of its citizens acted against ours. Prove A) that Iran started the fight, and B) that it supported the operation against us, and you'll have an argument.
