The question of whether the President has the constitutional power to authorize covert paramilitary actions or shadow wars against other nations or entities first surfaced at the beginnings of the American republic and continues to vex policymakers today.
Words are imperfect instruments for conveying ideas, and interpreting the intended meaning of words is often a challenge, especially when more than two centuries have passed since the words were written and their meanings have evolved over the years. For example, the terms “executive power” and “declare war” had widely understood meanings when the Constitution was written.
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.
