Germany did not make this decision based on what is right and wrong but most likely because there is so much savagery and brutality that the people of the world can take before turning against the Jews. The Christian countries of the West and specially of Europe are always very careful not to say anything that might offend the Jews because then the Jews are going to remind them of what happened in Europe between the Christians and the Jews. But the Arabs got nothing to do with that and today the European Jews have been confirmed to be 100% Europe according to their own DNA and therefore they used a fiction when they claimed to be the precious Hebrews returning home to Palestine. Without using that fiction, they would never have managed to occupy Palestine.
