You don't get it. It couldn't have been spent on something else. If the day before 9/11 Congress had passed universal healthcare, free college, and basic income, they still would have spent this money on a war. Are you saying they could have said, oh we got attacked, let's estimate the cost of a war and put it into healthcare?
