Arnold Schwarzenegger's father was a MP for the Nazis. He was physically abusive to Arnold, whose childhood in his native country after the war was fuckin' rough, and as a young man Arnold had basically no money and no prospects to his name other than a handful of people around him who believed in him. Among the dreams he had since he was a little kid was being able to move to the United States and have a free and rewarding life there.
He's aware of the dream of democracy and freedom and what it means in a way that's a hell of a lot more impactful on him than almost all native-born people and certainly most people in Washington. He can hear his disgust for Trump and everything he stands for in every one of these. His speech after January 6th, where he takes out the Conan the Barbarian sword and talks about what democracy means to him, is fuckin' dynamite.
