The greatest danger to America is when a dictator is in charge and controls thoughts. You need two elements to do this. The evil intent of power and AI algorithms feeding anger, fear, uncertainty and doubt to the US citizens, at least enough of them to create an angry mob.
Stalin and Hitler used extreme punishment for thoughts discovered by a small number of thought police and policies that turned neighbors and children against anyone with criticism. Trump can use AI.

Trump promised to use the Army to arrest anyone who criticizes him. He can use AI to monitor and isolate any citizen that criticizes Trump MAGA.
