Democracy doesn't work in a US-dominant world. My country is nowhere near Africa yet there have been 7 coup attemps, 4 successful, most backed by US in her 100 year history[2]. The last one didn't succeed and the US is currently protecting the leader of the attempt, refusing to give him us back.

Arab leaders are likewise domestically widely regarded as sockpuppets of the USA. On the rare occasion a democratic election happens, the president suddenly dies, gets assasinated, or a coup d'état happens and gets hanged. Off the top of my head see [2] for an example.

This is not to say democracy would work in a Russia- or China- dominant world. It seems democracy only works for the nations who can sufficiently defend against infiltration by the NSA/foreign intelligence agency of the dominant power. And I don't think that's easy, or feasible at all. You can't expect an African nation of 10M population who gained independence 2 decades ago to have the skilled people to be able to conduct this sort of intelligence operations.

And of course, the US is the peacekeeper of the world, only bringing democracy and welfare to the poor nations held back by their authoritarian leaders and backward ideologies and religions. Long live Imperium Americana!
