Ah, I see where you are going.
I am sure that the Banderites do not celebrate the Soviet Victory over Nazi Germany. The OUN-UPA had seen Nazi Germany as their ally, their best and greatest hope for creating a Ukrainian State. When the Soviets took back Ukraine (and Galicia) in 1944 it must have been a very sad day for the Banderites - which is why they all f--ed off to Canada, USA, Argentina, Australian and elsewhere.
This is also why the Banderites - and Bandera himself - were always so valuable to the USA and its allies - and why the Banderites were given such comfortable accommodation in the West. "The enemy of my enemy is my friend".
As I mention in my article, the Banderites did not see the Soviet victory as a victory. They did not see the liberation of Ukraine from Nazi Germany as a liberation. On the contrary, they saw these events as disasters - as massive and catastrophic losses to the Russian Imperium and the disastrous slipping of the Ukrainian people once more under the boot-heel of the "Great Russian Enemy".
No wonder then, that Stepan Bandera was able to get a cushy job working for the CIA and the BND after the war. Had the KGB not finally caught up with him, he might still be relaxing in some sumptuous Bavarian spa.
