Drift: The Unmooring of American Military Power is a 2012 book by Rachel Maddow. Her first book, Drift explores the premise that the manner in which the United States goes to war has gradually become more secretive and less democratic. In Drift, Maddow examines how American declarations of war have incrementally shifted from being Congressionally approved to being centralized in the hands of the American President. The book's scope spans from the Vietnam War to the wars in Iraq and Afghanistan.
