You know that whole thing about laws being unconstitutional and how much time goes into such questions?
Guess what. We don't even have that.
In the UK, the Queen signs a bill into law, that's it. It's constitutional.
If a law doesn't work well, we write a new bill and pass that.
It's a lot simpler.
If a bill is crackers, well, the Queen won't sign it. A Prime Minister can't do a coup. The army answers to the monarch. But if the government wants to ban hand guns, say, well, it passes a law and that's that. No handguns. So things can change and people like Trump don't get anywhere.
It's not perfect but it feels like evolution happens. It's that which I think is the big US problem. Change is too hard.
