and nothing out of the ordinary could possibly happen? Like sending military to California despite it being against the law? ICE not caring about habeus corpus? SCOTUS making every possible ruling to give Trump more power? Republican party being completely complicit and even cheering him on? Even those strikes against Iran were if I'm not mistaken borderline against Constitution (prez can't start a war).

I made a question, your answer tells me you have no clue either. There is no-one in the US left with the power and willingness to stop him. Army top brass and sec of defense are now his allies. FBI, CIA are lead by his loyalists. SCOTUS is in his pocket. Congress doesn't want to do anything against him. Lower courts were just ruled to not have any power over him.
