who appointed us as the world's enforcer? are we the mafia of the world? if the entire world condemns it why is the USA the only one who has to take action?
We appointed ourselves, after WWII. Because we're the richest and the biggest, and mostly because if we don't try to stop world wars, we repeatedly get dragged into them, as we saw in WWI and WWII.
This was a good policy, but it has worn out now. We keep making pissant wars that always lose and take ten years losing. (Vietnam, Iraq, Afghanistan ---- soon Syria and Iran.) IOur world policeman role worked pretty well to stop WWIII for long time, nearly 70 years, but now we're more likely to be starting WWIII, so it's time for a different foreign policy, IMO.
Nothing lasts forever and this is not working.
