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?
World War 3 isn’t the answer, not with the biggest players in the defense industry being US based.
If the change in power were due to military power, the EU would have to switch to not relying on the US…which is what they’re starting to do!
A more reasonable scenario would be financial: the world deciding to not use the US dollar as the currency standard and start cashing in the US debt.
