What I know about Holocaust: Quetion 1

Holocuast was a disaster where Hitler, a German leader, put Jews in camps and killed them all. I think this came from the belief that Jews, a smart people and the advisor in World War 1, led the president go to the wrong side and made wrong decisions. Hitler was basically saying this to make something up. Hitler wasn't a politician, he was an artist but he got the president or the dictartorship because people were pushing him to be the president. A lot of Jews were killed and they didn't have hopes. It was a massacre, but it was like Americans putting Japanese in training camp, except Germans killed Jews painfully like those poison gases. In Germany they are trying to teach that Hitler was wrong, and Holocaust should never happen again to the students.
