Answer:
Propaganda
Step-by-step explanation:
Hitler used flashy signs and brilliant parades to show what it would be like to be a nazi. This allowed him to become leader of Germany. He then recruited a massive army of nazi soldiers. They were taught to think like hitler (in the sense of racism and world domination) and act upon these desires. This was mainly done theeough Hitler Youth because the younger minds were easier to manipulate. Hitler would also used flouride (which drops IQ for a time when taken in a larger dose than is in toothpaste) to lower soldiers IQ so they would blindly follow him and do everything he said.
