Civilian casualties are a fact of war. The Pentagon, we’re told, does its best to minimize them but war is messy and it’s impossible to achieve the number zero. Unless you’re talking about Somalia. America has been at war in the African country for years and, according to the Pentagon, it has conducted that war with almost no civilian casualties. Amnesty International—a non-governmental organization focused on human rights—says that’s not true and has conducted its own investigation into the war and uncovered evidence of civilian casualties.
