since the thread behind your link debunks something else, the false claim that a 'rebel commander' said he 'knew' they had Buks when in fact he said the exact opposite.
Here is a short description of what Bandera stands for from another source:
Historian Karel Berkhoff, among others, has shown that Bandera, his deputies, and the Nazis shared a key obsession, namely the notion that the Jews in Ukraine were behind Communism and Stalinist imperialism and must be destroyed. The Jews of the Soviet Union, read a Banderist statement, are the most loyal supporters of the Bolshevik Regime and the vanguard of Muscovite imperialism in the Ukraine. When the Germans invaded the USSR in June 1941 and captured the East Galician capital of Lvov, Banderas lieutenants issued a declaration of independence in his name. They further promised to work closely with Hitler, then helped to launch a pogrom that killed four thousand Lvov Jews in a few days, using weapons ranging from guns to metal poles. We will lay your heads at Hitlers feet, a Banderist pamphlet proclaimed to Ukrainian Jews.
The Germans intended to keep Ukraine for themselves. They arrested Bandera for his intransigence on the issue of independence, but released him in 1944 when it appeared that his popularity with Ukrainians might help stem the Soviet advance. But whatever their disappointment with the Germans, the Banderists never disagreed with their Jewish policy in Ukraine, which eventually killed over 1.5 million Ukrainian Jews.
