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?
The EU, China and other major trading partners (many of which are EU afilliates like Japan) could cripple the US overnight by dumping american bonds and finding new trading partners. This is already happening though in a very slow way designed to minimize damage.
