Reason's January 2015 issue takes a close look at the libertarian take on foreign policy. Editor in chief Matt Welch discusses the reality and propaganda of war, while Will Ruger, Sheldon Richman, Fernando R. Teson, and Christopher Preble go in search of libertarian realism on the international scene. Veronique de Rugy says foreign aid is a failure, and Sen. Rand Paul (R-Ky.) tell us when America should rattle its saber. Jacob Sullum warns about mission creep at the CDC. Plus, see the usual favorites, including Citings, Brickbats, and the always-curious Artifact.
