Professor Turner argues that Congress’s power to “declare war” and issue letters of marque and reprisal is an irrelevant “anachronism” in today’s world, and was virtually irrelevant even in 1787. According to Turner, the Declare War Clause only prevents the President from launching “a major aggressive war.” In his view, the President has the power to launch “minor” aggressive wars and even initiate “major” warfare (“major” is not defined) when such warfare can broadly be termed “defensive,” a vague term also not defined by Turner. Of course, no sane President would openly claim to launch an “aggressive” (or in eighteenth century parlance, an unjust war).
For example, President George W. Bush asserted that the 2003 invasion of Iraq was “defensive” although Iraq had neither attacked us nor was imminently threatening to do so, and the invasion was widely viewed by the world community as violative of the U.N. Charter. Turner’s interpretation of the Declare War Clause, of which James Madison wrote, “in no part of the Constitution is more wisdom to be found,” reduces this important provision to a virtual nullity, easily evaded by the executive’s claim that a war is either “defensive,” or not “major.”
