I'm sorry to be that blunt but if you don't understand the value of rule of law, the difference in incentives, the consequences of separation of powers, I can't even grasp what kind of perspective you can build. It's genuinely baffling to me.
The US is a democracy, and people are given many procedural and substantive rights, even Guantanamo detainees (we can argue if Boumediene had any practical effect, but we wouldn't have seen the same from China).
But Americans are under the impression that what the world sees is what they mostly see -- the domestic side. And to a certain extent, they do thanks to its cultural influence. This democracy/rule of law, however, is completely absent in way it behaves outside its borders and it's now clearer than ever to everyone that the US is the biggest source of instability in the world. More than Russia. Certainly more than China.
