This is the story of Han's twisted brainwashing and ultimate demise under the rules of the Nazi state. During WWII, the whole US was mobilized to fight it and Hollywood was no different. Disney did many comical cartoons of the war as well as numerous training films but it reached its propaganda pinnacle with "Eduction for Death". It's a great piece of animation as well as WWII-era propaganda. Not your feel good flick but still may make you laugh once. Maybe. Give it a gander here.
