Saturday marks the 20th anniversary of the 9/11 attacks, after which the U.S. launched its counterterrorism campaign.
Yet its self-serving "war on terror" has brought even more chaos, destruction and death to the world over the past 20 years.
The Costs of War project of Brown University, a leading U.S. research university, has found that the number of people killed directly in the violence of America's post-9/11 wars in Afghanistan, Pakistan, Iraq, Syria, Yemen and elsewhere is estimated at more than 900,000.
