Soviet Union did exactly that - they had gulags.

North Korea is doing exactly that as we speak.

Most of today's elite countries have unspeakable atrocities under their belt, even if you only consider the post-1900 modern era.

i think about this too. hell, if hitler hadn't invaded russia / western europe the nazi's might still hold central europe

I realize this might be wrong and based on not reading enough history about it, but I’ve always understood that the Holocaust was not well documented until after the war.

Obviously many people fleeing Germany and the occupied countries during that period, knew something bad was happening, but overall, it’s my understanding that before and during the war, the rest of the world really wasn’t aware, or at least not aware about how bad it was.

It was the invasion of other countries that was cause to fight Germany. It was much less of a humanitarian act, though after the war it’s easy to paint it as one.

There’s more truth to this statement than I am comfortable with.

That is unfortunately most likely true. Stalin is a case in point.

yep, what Stalin did in Ukraine was comparable, while helpful idiots in Western press were praising him for education and healthcare

At least during Nazi Germany there was some interest in helping Jews escape. Yes, instances when ships of Jewish refugees were turned away from e.g. the USA have gone down in infamy, but there were still things like the Kindertransport. When it comes to the plight of the Uighurs, even fellow Muslim countries are loathe to provide any big public help due to the fear of alienating China.
