November 2018 marked the centenary of the end of World War I (1914–18), the first great international conflict of the twentieth century. After almost 100 years of relative peace, the major European nations went into a war that left millions dead, empires toppled, and a continent devastated. The conflict and its divisive peace left a legacy that helped give rise to totalitarian ideologies, like Communism, Fascism, and Nazism, and paved the way for World War II and the Holocaust.
Beginning in 1979, the Office of Special Investigations (OSI) opened hundreds of investigations and initiated proceedings of Nazi war criminals. These investigations lead to the denaturalization and/or removal of more than 100 Nazi offenders from the United States.Despite initial predictions that its work would soon be finished, OSI has been active for over 25 years.
