> You're confusing Trump's mouth with how the US political system actually functions.
I'm not confusing anything, right now Trump's mouth IS the political system in the US. Republicans control every aspect of the government completely, all the way through to the checks of the US Supreme Court.
No Republican has enough backbone to stand up to Trump, and if they do gain a backbone to stand up to Trump at all, like MTG, they exit politics quickly. Thomas Massie is the closest to somebody who is standing up to Trump. If Republicans in the Senate were willing to stay in office yet defect from the party, that would be enough to stand up to Trump, but even that's not happening.
Right now, the US is in a position not unlike Imperial Japan, right before they launched an attack on the US, forcing the US into WW2. High Command wants somebody to stand up and stop the obviously bad action, but nobody is willing to make the short-term sacrifice for the long-term good.
