Can someone explain to me?

1. Hitler was not insane. Or maybe he was, but then you'd have to call Lenin insane too. Or anybody following a murderous ideology until its logical end.
Hitler had the personality of an artist- and many artists are violent, uneven, megalomaniac persons. But Hitler was also an idle, ungifted artist. So he would have ended up as a peddler would the times have been any better.
But there are situations, when idle, ungifted people can rise up. Just because they have a big mouth.
(Or because of a class system. See Winston Churchill.)

2. I don't really understand that question. What people knew what was happening? And who should have ended it?

1. I guess you would have to say that Hitler was indeed very insane, but he was also very smart. You ask the same question as Ron Jones was once asked, he was the inspiration for the film "The Wave", he was a history teacher in the US in the late 60's. His students asked him how it was possible that Hitler had such an appeal, that he rose so quickly to fame. I strongly advise you to watch this film, very much an eye-opener (and obligatory study material over at our schools (in Holland)).
Plus, Germany was still on its ass, still suffering from the economic blows of WWI. The people saught for someone to take their hands and lead them to better times. Hitler offered that hand, at the right time but with all the wrong intentions.

2. The world was at War. It wasn't just a question of pulling the plug, the entire world was in a political crisis. Hitler didn't just pop up and opened his mass destruction camps, he worked gradually, first, forcing all Jews into getto's, then into work camps, and later, much later the horrible concentration camps. On top of that, nobody exactly knew what was going on in these camps, the Jews had heard rumours of course, and they knew that going there wasn't a good thing. When taken to Auschwitz, the people weren't told that they were going to be gassed, they were told that they would have to take a shower. Many people were afraid and also unaware. Many Germans never even knew about concentration camps, about the killings. Neither did the Americans and the British that came to free Europe.
I don't really understand your point about they money for the concentration camps, the camps were build on Hitlers orders, he was at that point, the highest boss and why would anybody disagree with him? Disagreeing, would mean your death.

War and politics is complicated and difficult, if you want to know more about WWII, ask your history teacher or get some literature on this topic. Try wikipedia, there is a lot of info about it there.



As a Final Touch, God Created the Dutch

1) desperate times call for desperate measures.

2) i had a friend who was fighting in world war two, and they had no idea that the concentration camps existed, and the fact is the majority of people didn't even know about them. i suggest watching auzwitch, it was a special on the history channel a few years ago. it helps you get more of a perspective on how the world was in the dark about, and how the military knew, but there wasnt much they could do. (they didnt know about the mass amount of people that were being killed, they just knew that jews, gypies, homosexuals, and blacks were being shipped to work camps)

1. One reason I've gathered is that people of that time saw two possible solutions to Germany's problems: communism and nazism. Most people thought nazism was the safer of the two since voting for a communist government might make the Soviet union come to "help out". At the time the nazis came to power there was no big nazi nation anywhere in the world.

2. I agree with most other comments on this, but I'd also like to add an experiment in which people's willingness to obey an authoritative figure was measured with the rather disturbing result that regardless of who you were or were you came from there is an about 60-65 percent risk that you are willing to kill another person if ordered to do so by an authoritative figure (read about the experiment here: http://en.wikipedia.org/wiki/Milgram_experiment )

A few other psychological factors influencing both above points are group pressure and people's urge to be conformant (see for instance http://www.age-of-the-sage.org/psychology/social/asch_conformity.html )

It may seem obvious what to do when we have the answers... but we only ever get them after the fact. And, by the way, "after-the-facts reasoning" is another psychological phenomenon making it so hard for us to understand what was going through the heads of the people "allowing" Hitler, the second world war, and the holocaust.

Simply put, after-the-facts reasoning means that we reason differently about questions and problems before and after we have the correct answers. In this case it means we're reasoning differently about nazi-germany, the holocaust etc today than people did when it was happening... mainly because as you point out, today we know how insanely stupid it was... once people started to understand what was going on/had been going on, it had gone too far and most people knew they'd have to risk their lives if they wanted to oppose themselves. (You might want to check out "Sophie Scholl" -- http://en.wikipedia.org/wiki/Sophie_Scholl, there's also been done at least one movie -- if you want to get an idea about what people opposing the system was risking).
