hitler quote?

i think i read yesterday article in newspaper titled 'Mungkin ada benarnya Hitler' or something like that.. tentang apa sebab Hitler membunuh Jewish semasa pemerintahan dia dlu.. Hitler beranggapan bahawa bangsa Yahudi ni adalah sangat merbahaya dan mengancam dunia.. He killed around 5 million of jewish peoples at that time..

this morning received a forwarded email that i think most of us will received it by now..I wonder if its really his quote..

Quote from Hitler's
