This inquiry leads students through an investigation of the importance words have in easing or escalating diplomatic tensions. By investigating the compelling question “Can words lead to war?”, students evaluate the historical context of American tensions with North Korea. The formative performance tasks build on knowledge and skills through the course of the inquiry and help students trace the evolution of the contemporary Korean Conflict through an analysis of how contemporary American presidents have communicated in general and specifically with North Korea. Students create an evidence-based argument about whether words can lead to war, and about the implications of social media for international diplomacy.
