http://holocaust-history.org/short-essa ... jews.shtmlJews were the targets of the Holocaust because Hitler hated Jews and blamed them for all of the problems in the world. He especially blamed them for Germany's loss of World War I. Hitler told the German people that they could have won the first war, if Germany had not been "stabbed in the back" by the Jews and their conspirators.
Untrue on so many levels. Neither Hitler nor the NSDAP "blamed Jews for all problems in the world".
Their role within WW1 is a bit more complex as well. And I'd say this was generally realized by observers then.
Jews were to removed from Germany, because they were seen as an intrusive alien element in German society.
