The power is already curtailed if there's no one to enforce court rulings. An appropriate court says X, the administration just ignores it. How do you get enforcement when law enforcement at every level is willing to answer only to the Executive in Chief?

I think it's far worse - the military en masse broke their promise to uphold the constitution and instead supported Trump and Hegseth, including committing war crimes and deploying into USA cities. Not to mention going to war (twice) without authority.

If USA becomes a constitutional democracy again will you expel all those who failed to uphold the constitution? Essentially the whole military except those who quit.

Surely you can't move forward without removing honours and pensions, and imprisoning, all those in the chain of command who ordered firing on civilian sailors/shipwrecked combatants (take your pick which), for a single example.

How can you inoculate against these things happening again?
