Those noble Aryan Nationalsocialists only wanted to secure a future for White children, but the Big Bad jew didn't like it – probably because he wanted to secure the existence of his own race –, so he divided the Aryan countries into competing groups: the Aryan Slav was forced to fight his Aryan German brother. The jewish revolutionaries decided not to completely eradicate the Nordic Russians (descendants of Vikings), so they used them for slave labour and send them to fight their White brothers.
The Nationalsocialist Germany was the last bastion of hope for the White race. Hitler's Fatherland was simply overrun by the huge jewish-led armies of slaves.
Also, don't forget that the French Revolution was in fact a jewish war against the Nordic French aristocracy.
