This video contains incorrect information. The Yalta conference, resulting in the 'Yalta Agreement' between Russia, Britain and the US, occurred as a desperate move to fight Germany - who were still very much in the war. Stalin agreed to release Polish troops from Russian POW camps so that they could fight Germany. The Poles did not know though that their tremendous efforts would result in the Polish airforce pilots (who were credited with being the reason the Battle of Britain was won by the British) being handed back to Stalin at the end of the war. They fought so bravely believing that they were also fighting for their own freedom - but they weren't. After the war was won, there was a big military parade past the British king - but the Poles were not invited. Instead, they were told that the pilots were to be handed back to Stalin - a fate worse than death. Over thirty of them committed suicide. Yet this vile betrayal and travesty by Britain is never mentioned.
