What coup attempts are you talking about? Let’s try to focus on coups that were at least attempted or has any substantial evidence of being in the works.

I am not talking about coup attempts. I am exactly talking about lack of coup attempts in countries, where you would expect superpowers to start one if they could. But they can’t. I failed coup attempt already signals instability of your system. Or do you believe a good political system should have regular coup attempts that have to be suppressed by force?
