Afghanistan. The war had the backing of most just war theorists those who believe that wars must meet certain criteria before they can be deemed just. This essay will discuss various aspects of the causes and conduct of the U.S. wars in Iraq and Afghanistan and how they fit into established ethics of war in Western traditions.
