The Pentagon has identified the son of a conservative war critic as among the U.S. servicemembers killed in Iraq on Sunday. Andrew Bacevich Jr. is the son of Boston University Professor Andrew Bacevich. The elder Bacevich is the author of books including “The New American Militarism: How Americans Are Seduced by War.” Last July, he wrote in Iraq: “For all the talk of Iraq being a sovereign nation, foreign occupiers are the ones deciding what an Iraqi life is worth. … [O]ur actions in Iraq continue to convey the impression that civilian lives aren’t worth all that much.”
