During the WWII, armies of Europe – namely Germany, Italy, France, Romania, Slovakia, Croatia, Finland, Belgium, and Poland killed millions of Soviet civilians, hence Russia should demand financial compensations from the EU for genocide. Nineteen million Soviet people, civilians, non-combatants, were killed by European armies.
During the WWII, ‘armies of Europe’ did not invade the USSR. It was the Axis powers, opposed by the Allied powers headed by France, the UK, the US and the USSR. Some European countries had been forced by Nazi Germany to join the Axis powers, but then, after capitulation to the Soviet army, supported the Allied powers. Poland was seized and then divided by Hitler and Stalin in 1939 and then, after WWII, occupied by the USSR as were large parts of Eastern Europe. The EU was established after WWII.
