number of US civilians killed on US soil in the 9-11 attacks.
What have we spent to avenge the deaths and prevent future loss of life?
The “Costs of War” project, based at Brown University, estimates that the total monetary cost — including long-term veterans care — of the conflicts in Afghanistan, Iraq and Pakistan may eventually total as much as $4 trillion.”
“New York Times estimated that the United States spent $3.3 trillion in the decade after the 9/11 attacks”
“A Congressional Budget Office report estimates that by 2020 the price of treating Iraq and Afghanistan veterans alone could be more than $8 billion annually.”
So far, just dollars. We can always print more of those.
people killed overall as a result of the conflicts
“The Brown University project estimated … all countries involved have lost a total of 31,000 uniformed service members and military contractors. [It’s] estimated in 2011 that between 152,280 and 192,550 civilians in Afghanistan, Iraq and Pakistan have died as a “result of the fighting at the hands of all parties.” …March 2013 … researchers revised the civilian total estimate to 200,000; and they estimated that 330,000 people had been killed overall as a result of the conflicts, accounting for all soldiers, militants, police, contractors, journalists, humanitarian workers and civilians involved.”
