Consider how U.S. foreign policy changed in the aftermath of WWII, and analyze the philosophical, geopolitical, and economic factors that  influenced these changes. In this interactive lesson from GBH, students develop a written argument in response to the question “How did U.S. foreign policy change in the aftermath of WWII, and what influenced these changes?” They gather evidence from videos featuring historian Ben Weber and from primary source speeches, documents, and images. This resource was originally developed for the Writing in U.S. History collection, the Calderwood Writing Course: U.S. History.
