All that was documented was jews getting taken to the camps, one part of the story was incredibly well documented, the rest is assumed. 90 percent true other than the 10 percent where they were actually killed which means they story is 100 percent bullshit. In the gulag archipelago Solzhenitsyn spoke to a former inmate and found that the pows that were 'liberated' from the 'death' camps were immediately arrested for collaboration with the Nazis because the (((Soviets))) had already decided that the Holocaust happened and anyone surviving must have collaborated to survive. Truth is that they were arrested so that they couldn't tell the truth to anyone.
