1-The post WW2 books written by the wartime leaders Churchill, Eisenhower, and DeGaule never mentioned any gas being used or any planned, systematic extermination of anyone nor do they mention millions or even hundreds of thousands of people dying. There is no paper evidence except the Jewish books, journals and histories. In my opinion it is a little strange, the written word from middle ages was just fine to read and study but there is nothing found about the holocaust from the diffrent point of view except the Jewish one so it's a really strong argument.
