Hitler and his close circle were Pagans/Spiritual Satanists. It wasn't called Spiritual Satanism back then, but it's exactly the same thing.
Europe and especially Germany was in ruins after WW1, and the jews were planning to invade the entirety of Europe via the USSR before the 1960's. Hitler knew this and tried to unite Europe against the USSR, but many European countries were owned or influenced by jewish banksters of the US and Britain, and were aggressive towards Germany. This was the reason National Socialist Germany "expanded", it was actually a way to ensure no other war would occur during the invasion of the USSR.
Hitler didn't start WW2, he was forced into it. Polish jews were murdering Germans in Poland and Hitler sent a referendum to Poland to retain peace and provide security for Germans in Poland. Under the orders of the (((US Congress))), Poland refused and Hitler had to invade to impose stability. Britain and France declared war on Germany but didn't act immediately. This gave Germany the time to prepare and invade first. Germany had tanks and radio communication, while France still used horses and flags as signals in the battlefield. In Dunkirk, the Germans allowed hundreds of British soldiers to flee back to England, even though they could have killed them all. Hitler didn't want to kill all these Gentiles.
Everywhere Germany expanded, there were thousands of volunteers enlisting in the Waffen SS to fight the USSR. There were Poles, Danes, Norwegians, Finns, Frenchmen, Italians, Spaniards, Portuguese, Dutch, Belgians, Walonians, Croatians, Serbs, Bosniaks, Hungarians, Albanians, Romanians, Bulgarians, Greeks, Ukrainians, Russians (!), Tatars, Uzbeks, Palestinians, Egyptians, Arabs, Iraqis, Syrians, Turks, and some more races that fought in the Wehrmacht and/or the Waffen SS.
Specifically in Greece, Hitler only invaded to help Italy, and to kick the British gangsters out. Then, Britain and the US imposed an embargo on the National Socialist "Hellenic State" and hundreds of millions died of starvation. German trucks were providing both the soldiers and the population with food, but there were people who were assigning 10-year-old children to steal from these trucks. After the war, a civil war was imposed on Greece and the communists were kidnapping children to use them as terrorists in their ranks.
The real history of WW2 is much, much different from any mainstream explanation. I could write an entire book on this.
