Jews,besides few exceptions,were hated through whole europe since christianity rose to the power,there were multiple jews genocides in european history,so hitler didn't do anything new...except he did it in a really huge scale...but nazis killed much more poles and russians than jews,slavs were his 'number two' in his extermination list,but who cares nowadays,jews were most damaged nation (wich is b/s)
It's just a matter of propaganda,jews wont let anyone forget 'bout their grievance,so nobody will mention stalin,pol-pot,that serbian guy (karadzic?)
