The WTO is exposed to significant political risks deriving from both the abusive employment of the national security argument, as well as the use of the WTO dispute settlement system to address this problem. This article explores the implications of the first WTO panel decision, adopted in April 2019, in which the argument of ‘essential security interests’ was employed to justify trade restrictions. Article XXI of the GATT 1994 now tends to be invoked in other ongoing disputes, notably by the United States in the dispute settlement cases involving its barriers to steel and aluminum. The article argues that pathways other than WTO litigation should be explored to deal with trade barriers adopted under the argument of national security and, despite the absence of simple solutions, it considers some possible alternatives.
