It backfired. The sanctions were too harsh and coupled with the general financial depression of the 30's German citizens suffered even more than many of their European neighbors. Hitler gained popularity by promising prosperity for Germans, blamed much of their condition on the Jews and after getting into power he quietly built a powerful army. He was able to convince Germans that the Aryan race, not just the Caucasians, but a specific sub-group of Caucasians with specific physical characteristics was superior to all others. These he called the "master race". Many of the Germans loved to hear that. It proved what some already believed, and the others wanted to think of themselves as special. Hitler was livid when a black man from the United States won a race in the Olympics. He believed that Germans should have won everything. Members of the NAZI party were not just political ideologues, they were hand picked for matching the Aryan profile. By believing that all others were inferior and therefore less worthy, Germans were justified in their actions. Germans truly believed that they could manage the world far more efficiently. They believed that the Jews would always be greedy and always run the banks and other financial institutions and that the world could not function as long as they lived. NAZI
