Hasn’t this been known for DECADES?
First released in 1984.
Yes...they knew within months about what was going on.
The question was: what were they going to do about it?
Answer...not much to be done. Since the means to stop it were not immediately at hand, and there was a war to be won.
Most definitely.
“Hasn’t this been known for DECADES?”
yes.
it’s fake news that this is new information.
and furthermore, what could the allies have done to stop the mass killing other than destroy those doing it (which they ultimately did? Bomb the trains carrying the victims or bomb the concentration camps? All that would do is make us complicit in the slaughter of innocents.
There is evidence all over the place that the extermination camps were no secret to anybody. This was known in the earliest days of the origination of the camps..
The pope and the "neutrals" in Switzerland and Sweden were actually complicit in their non-action when the information was made available to them.
What could the allies do about them? Nothing until they physically overran the territory where the camps were located. Eisenhower actually demanded an entire army of eyewitnesses because he knew there would be future denial that this holocaust ever occurred. Stalin could have cared less. He killed as many or more people in his reign of terror.
There was no way anyone could bring social pressure on Hitler to shut down the camps. Speculation on that is just dumb
Yes! Allies knew from the very start, as did the German public.
Impossible to keep this horror secret for very long.
Yep. Known at the time among European citizens.
