Which State has caused the most civilian deaths around the world after 9/11?

A study reveals that U.S. military forces were directly responsible for about 10 to 15 million deaths during the Korean and Vietnam Wars and the two Iraq Wars. The American public probably is not aware of these numbers and knows even less about the proxy wars for which the United States is also responsible. In the later wars, there were between nine and 14 million deaths in Afghanistan, Angola, Democratic Republic of the Congo, East Timor, Guatemala, Indonesia, Pakistan and Sudan.
