So now we can add “directly capturing a sovereign leader” to the list of crap the US has done. So what do you think will actually be “the straw that broke the camels back” for world leaders to actually do something? Think it’ll be significant or something mundane?
Most of these answers here are not viable because the US has leverage in almost every nation on earth.
Venezuela, Iran, Russia, China, etc are the exception, hence why they are sanctioned (and constantly suffering problems with every new CIA project) bar China which is locked in a trade war and has a sizable military to back themselves up.
You would realistically require a counter world power that offers an alternative to the US system, which used to be the USSR which no longer exists.
China is poised as the next superpower, but they haven’t made any significant moves in that regard because they are wary of the USSR’s downfall, and have no intention of engaging the USA in that manner (yet).
Everyone in the UN, despite all their cries, will fall in line when threatened, aside from the aforementioned exceptions.
