Democracy Now! speaks to William Hartung about his new book “The Trillion Dollar War Machine” and who profits from the United States’ runaway military spending that fuels foreign wars. Hartung says that U.S. policy is “based on profit” and calls for a rethinking of our foreign entanglements. “We haven’t won a war in this century. We’ve caused immense harm. We’ve spent $8 trillion,” he says.
