There are many lies in this interview.
Poland did not cause World War II. It was caused by Germany and Adolf Hitler who was democratically elected by the Germans.
The Germans then built concentration camps on Polish lands which were mainly intended to kill Poles.
Poland did not persecute the Ukrainians. It was the Ukrainians who committed genocide against the Poles: they burned them in barns and pregnant women had their babies ripped out of their wombs and put there cats - these are the memories of the survivors of the genocide in Volhynia.
This is the real story, not the one Putin is telling.
