No - the Holocaust was the result of a general distrust and jealousness to the jewish success in financial issues within a economy depression. This general thinking was pushed by the Nazis in a very ugly way to give them the face of an enemy within the own state.
Hitler did some radical things to raise the economy and people started to trust him because they saw that things get better. However - Hitler pushed his personal hate against jewish people and people also believed in this words, too - because of the general distrust in jewish people.
It had nothing to do with a conspiracy that people believed in - not from what i´ve learned about the issue. I have no clue at wich point the "jewish conspiracy" started and for what reason. I even didn´t know much about the zionism before i listened to boards, websites and radio-shows after seeing Loose Change - 3 months ago.
But my "alarm bells" are ringing if i hear such ideas like Eric "i did not do much research about the holocaust

" Hufschmids: "Holohoax - Joooos did it".
