It doesn't matter if they knew or not. They had a military objective to destroy. Wars are lives lost and families destroyed because of the failures of diplomacy and politics.
If the politicians and the diplomats don't have the stomach for dead children, they shouldn't have failed at diplomacy, and they shouldn't risk the lives of America's military sons and daughters to cover their @$$es and cleanup up their failures.
When you ask someone to risk their lives, you do everything you can to bring them home safely to their families.
When diplomats and politicians fail, either Iranian familes get torn apart or American families get torn apart. The diplomats and the politicians, on all sides, are responsible for all deaths - civilian and military.
If the Iranian regime does not value the lives of its own citizens, why should we?
If Americans do not have the stomach for the fight against Iran, the American Government should seek an unconditional armistice or ceasefire, and withdraw from the Mideast. It is a sin for politicians to commit their constituents to die in a half-ass war.
Leave fighting wars to the warriors willing to do everything required for attaning the clear, well-defined objectives specified by civilian politicians and diplomats. Otherwise, dont' start wars.
The most moral and humanitarian acts of war are not starting them and bringing them to end as soon as possible.
Wars are savagery that must be fought savagely to bring them to peaceful conclusion.
Let politicians and diplomats send their own children to die for their mistakes, shortcomings, and failures instead of committing other families' children to be captured, injured, maimed, disabled, or killled.
You’re assuming facts not in evidence. I asked a more fundamental question: did US planners know the school was there.
If they did, was there some absolutely overriding reason why the target could only be hit while school was in session, or could it have been hit at night or after hours.
The fact that collateral damage may be acceptable does not give one carte blanc to willy-nilly hit civilians who might be in the way.
