Why bring the constitution in line with Estonia's? What's special about them?

I think the above person is correct, and you are on the right track.

I'm not hopeful for a full Constitutional Convention, but every possible effort by any means must be made to put into law every "unwritten norm" that the Trump administration took advantage of.

Impeachment is the mechanism to remove a rogue president, and the entire GOP is party to a "soft coup" against the Constitution of the United States. I agree it will take a complete societal rejection of MAGA and the Unitary Executive theory for allies to ever trust the US again.
