Researcher Nicolas J S Davies put together a three-part investigation for Consortium News in 2018 to find out how many people had been killed in America’s post-9/11 wars. Part one covers Iraq, part two covers Afghanistan and Pakistan, and part three covers Libya, Syria, Yemen and Somalia. At the end of the series, Davies writes the following:
“Altogether, in the three parts of this report, I have estimated that America’s post-9/11 wars have killed about 6 million people. Maybe the true number is only 5 million. Or maybe it is 7 million. But I am quite certain that it is several millions.”
