The Waffen SS in fact had units from everywhere in Europe. There was a Muslim company from the Balkans, which had its own Imam and each platoon had its own Mullah. The indigenous Cossack people of Russia had an SS unit. There were also Scandinavian units, Spanish, Croatian, Romanian, Greek, Indian and French. Each of these groups fought alongside their German counterparts in coordinated movements, mostly on the Eastern front. Of course I'm aware of Nаzi stigma which was why I suggested the Croatian Ustaše instead, who were a similar force organized in their own country (which didn't exist until Italy and Germany helped them declare independence in 1941). They were a fascist nationalist unit which fought against the Soviets, local Communists, assorted partisans and the military of neighboring countries. The setting would be absolute chaos and perfect for an SO:TL style of gruesome, intense, and above all [i]meaningful[/i] chronicle of violence that I'm sure the team behind Yager could handle properly.

As a dictator it was clear that he make everthing possible to keep this war alive

Because the defeat was clear but he ignored it He said when germany lose it is fair when every german has to pay with his life for that.
