The document summarizes the history of refugee and immigration policy in the United States and Canada from the late 19th century through the recent Paris attacks, arguing that policy has long been framed around excluding minority groups in the name of security. Early policies implemented race-based quotas and bans on Asian and some European immigrants. During the Cold War, policies targeted communists. Following 9/11, policies became more exclusionary. The Paris attacks have further shifted policies towards greater securitization, despite long-standing trends of disproportionate impacts on minorities in the name of national security.
