Unless all countries come together, the idea of a 'world police' by any number of select countries is silly.

One nation being the 'world police' is even crazier.

We rely on coalitions nowadays to do much (Iraq, Haiti, Yemen, ....maybe Yemen again soon..., etc).

Coalitions are better than a single nation, but should really be an organization independent of any nations, that people trust; in the modern world, ideally would be the UN, which has peacekeeping forces, but I don't know if the trust is currently there with the UN, and a number of 'bad actors', namely because the UN doesn't serve that purpose, it is supposed to be a dialog between nations, not a unifying power, or protector/military force.

The good news on the US front, is for many coalitions to step in, the US is trying to take a back-seat, and have other nations lead them. Not that those other nations don't have concerns. I'm not up to date on it, but I believe Kenya was being sought to lead the coalition to Haiti to restore peace and order, but I believe there were concerns about the history of Kenyan police treatment in past coalitions. Still, the US should not be the one in-charge of world policing, though that is not to say they shouldn't be involved in any such action, just they are a piece of the puzzle, not the solution in and of itself.

I'm rambling too much. I think it's time for me to get off Lemmy for the day. Peace out.
