Yes if given the chance. Economically it's actually difficult to do so, as the Germans and Soviets learned. If you don't have to hide, it makes it even easier. And denial rhetoric, which has never changed, helps them greatly in achieving that goal.

"Well, we don't have evidence that these camps involve killings. So, we're not going to investigate it. We're going to do business as usual."

As a Polish-American, here's a fun one. Look up Jan Karski. The dude that personally witnessed the extermination camp atrocities, escaped and reported to Western Allies in WW2. Even met with FDR. Supreme Court Justice Felix Frankfurter who heard the reports, "I did not say that he was lying, I said that I could not believe him. There is a difference."

Saying you don't believe someone is the same as thinking they're lying. "I believe you, I just don't think you're telling the truth." Doesn't make sense. "I don't believe you, but I think you're telling the truth". Doesn't make sense either.

But this is why I get fired up to all Hell about this stuff. You don't want to believe it. Look up BBC reports of interviews with people who got out of these camps in China. I mean, if there's organ harvesting, I highly doubt they're waiting for a natural death. That's all we know right now. It's supremely hard to believe it can stop there.

History never, ever changes. It's just different names, different faces and different blood spilled. But it's always the same stories and the same lies.
