Ukraine
During the first years of World War II, Ukrainian nationalists collaborated with Nazis against Soviet Union hoping to reestablish Ukrainian independence or to get autonomy under the authority of Germany. Nationalists took part in mass murders of Jews, Roma people, and other victims of the Nazi regime. However, hopes of independence were ruined and Ukrainian nationalists created Ukrainian Insurgent Army which fought against Nazi Germany but against the Soviet Union (mainly Soviet partisans) for the most part. They failed to get independence. Most Ukrainians fought on the side of the Soviet Union and participated in the liberation of Ukraine from Nazi Germany.
