Talking About World War II: Would Hitler still have been able to create the Third Reich if he had not persecuted Jews and other minorities?

No. One of the main pillars of National Socialism was persecution of ethnic, social, and religious minorities, not only in Germany proper but in Europe on a continental level.

You have to keep in mind that Adolf Hitler’s goals were not simply to establish a one-party regime, “right the wrongs” that Germany perceived had been done to her after World War I, and rearm for self-defense. As early as the mid-1920s, Hitler stated his goals of destroying Jewish-Bolshevism, creating a Greater German Reich by conquering neighboring countries, and eventually invading the Soviet Union.

You also need to remember that Hitler did not “trick” ordinary Germans into following him, even when he made that leap into the abyss and invaded Poland in September of 1939. Many dedicated Nazis, including women and teenagers, were ecstatic at the outbreak of war and continued believing in der Fuhrer till the fortunes of war turned against their “Thousand Year Reich.” (Ordinary Germans, on the other hand, were only enthusiastic after Manstein’s Operation Sickle led to the quick victory over France in June of 1940. The euphoria only lasted until Hitler invaded Russia and declared war on the U.S. in 1941.)
