After World War II, the CIA recruited a group of Ukrainian nationalists who had collaborated with the Nazis in carrying out mass executions of Poles and Jews but who were now willing to work with the US against their common enemy, the Soviet Union.
The CIA protected their Ukrainian collaborators from war crimes charges and maintained a close working relationship until the fall of the USSR in 1991. Those Ukrainian nationalists founded the militant anti-Russian movement in Ukraine that leads the current war.
As with much of our present world, the war in Ukraine can only be understood by examining its roots in the Cold War.
Tomorrow I begin a 4-part live interactive course on the conflict that made our world.
