I think everyone needs to watch this especially British people for their role in all of this.
Nobody looks at the evils we committed against the Germans we think of Nazi Germany as evil and us as the good guys but look at the crimes of the Soviets who joined up with (arguably the greater evil?) and the crimes that the Allies committed during that war and ever since around the world... particularly America.
There really were no good guys in that war but there certainly has been the most one sided event in history that nobody is allowed to question.
This is why the documentary is so controversial because the Germans more than any people in history have been demonised to death as being evil. This movie gains sympathy for them, and shows what German people suffered.
But did you bother to watch?
