Not sure I’d agree Germany ever split or experienced a schism. It went one way for a while, then another, and the group as a whole admits not wanting to repeat it.
The relevant example here is Europe, not Germany. Germany regrets Hitler because Europe split, but the allies defeated it and then imposed their world view on the losers. The Nazis that disagreed were hung, imprisoned, killed or committed suicide. If Hitler had won this thread could have looked very different.
