CIA: Undermining and Nazifying Ukraine since 1953, page-70

The element (neon=nazi element in Ukraine) has a long history, of a long record that speaks for itself, when that record is actually known and elaborated on. The key organization in the coup (2014) that took place here recently was the Organization of Ukrainian Nationalists [OUN], or a specific branch of it known as the Banderas [OUN-B]. They’re the group behind the Svoboda party, which got a number of key positions in the new interim regime. The OUN goes back to the 1920s, when they split off from other groups, and, especially in the 1930s, began a campaign of assassinating and otherwise terrorizing people who didn’t agree with them.

As World War II approached, they made an alliance with the Nazi powers. They formed several military formations, so that when Germany invaded the Soviet Union in June 1941, they had several battalions that went into the main city at the time, where their base was, Lvov, or Lwow, it has a variety of spellings [Lviv today]. They went in, and there’s a documented history of them participating in the identification and rounding up Jews in that city, and assisting in executing several thousand citizens almost immediately. They were also involved in liquidating Polish group populations in other parts of Ukraine during the war.
