You do not want to go to Ukraine to fight on the side of the Bandera Nazis and you don’t want to fight on the side of the Russians either. It’s going to get ugly when the Nationalists start hurling their molotov cocktails at anyone who speaks Russian and looks Jewish. And you definitely don’t want to be caught in the crossfire when the Russians go after the Bandera Nazis.
Most Ukrainians aren't Nazis.
