Slow indoctrination was part of it. Hitler did not do everything all at once. Things were done in stages and people were kept in the dark about a lot of what was going on. His people lied about where they were taking Jews, Gays, Cripples and anyone else Hitler deemed not good enough. Slowly they chipped away until they had total control. The way they did it still has some denying it ever happened. It was sneaky, ruthless and horrendous.
because no one would believe something this horrific as the Holocaust was honestly going on therefore did nothing in the beginning when they could have saved so very many lives "lest we forget" is the motto I use and I write on this frequently.Get ahold of the Red Cross in Baltimore where they are STILL making reunions of family members.This is an important area of history to write about
There are quite a few documentaries about the Holocaust on Netflix. I recommend watching one or more of them. I find this phenomena very interesting, I wouldn't expect any nation to stand by and watch while an entire group of humans is wiped out. He killed approximately 13 million Jews, people with disabilities, protesters, and other people he found a reason to hate.
