The once who organized Genocide of Jews organized a political clown show.
Polen was on the same side of the Anglo-Saxonian axes who have conjured Hitler. In each KZ was an IBM office, many US-German corporations, like Opel, owned by G<M, have contributed to build up Hitlers Army, Poland has made agreement in 1934 with Hitler, dividing Thekhoslowakai, and the English have accepted it, as long as Hitler would move towards the borders of USSR to attack it.
Unfortunately for UK, before finally invading the nations of USSR he first turned against it's own masters, which ultimately lead to demise of the UK empire.
The fact that Poland's leadership didn't invite Russia to attend the memorial speaks for it self.
But it wont help. We will not forget who saved the Jewish nation, enabled the foundation of Israel - it was USSR under Stalin, and we wont forget the Polish genocide on Jews, which went in step with the collective west.
