My grandfather was a US Army Counterintelligence Agent during WW2, and let me tell you ten years after the war even he didn't know what really happened- the propaganda that came out at war's end was totally different than the actual facts. For instance, he never heard a single thing about nαzι "death camps" til years after the war. One would figure, as a special agent posted in Austria, he would have heard something during the war. Speaking of his post, he was undercover as an American businessman. That's right, Americans were free to travel to nαzι occupied zones all during the war. Many American companies did business with nαzι firms. No, WW2 was the last war that propagandists were able to so thoroughly alter- the widespread availability of cameras and video makes it almost impossible today, which is why we have to resort to assassinating leaders and staging fαℓѕє fℓαg attacks more than anything else these days. And do I need to mention all the baloney put out by the Fake Syrian Army? From them using the videos of Los Zetas drug gangs in Mexico, and claiming it is really footage of Syrian government atrocities, to showing crowds of "protesters" that happen to be waving the flags of wrong countries, the propagandists are all over everything.
Too bad they can't kill the internet, but hey the feds have control of all DNS servers now, starting today, so at least they can "disappear" people who know the truth too much.
