I mean, the US can't exactly be relied upon to fill that role over the next however many years of temper tantrums, graft and whatever else (nuking hurricanes?)
No. The seismic shift since Trumps first run has been felt. A bunch of, for lack of a better word, asshole world leaders running amuck: Assad, Putin, Netanyahu. Even N Korea is bolder. S Korea even tried to pull a military coup on democracy.
Power vacuums on the world stage matter. Trump created that. And we’ve failed to mend it either election since.
Lame duck President. Inertia. And now another run of Trump. We’re effectively done on the world stage, except for the occasional show of being a bully, probably, because it’s Trump and he wants to play with military toys.
Here’s the bigger problem.
China is boycotting all sales to our defense contractors. Take a minute to think about what that means. And will Trump continue to export what chips we do have to China this term as well? While distracting everyone with tariffs? There’s a modicum of security in military dominance, but it’s not us any more, it’s probably China.
For negotiating with Russia? It makes sense, they're an actual ally of Russia's that they rely on. We can waggle our finger at them all we'd like, & they could do the same to us, but that doesn't mean much. If China has something to say on the matter, however, their words would carry more weight.
Also, as others have pointed out, Beijing has been making lots of moves to become a key negotiator in places where America (or the west at-large) have failed (or are otherwise unable) to step in.
IDK, Syria has been a huge setback for the CCP.
Also, there is a growing wave of Chinese divestment among businesses everywhere, and the CCP is losing influence in Canada and Europe.
There is a growing will to break their addiction to cheap Chinese manufacturing.
Canada in particular hates the CCP, for the illegal police stations and for the kidnapping and ransom of the Michaels.
Machiavelli wrote about this. People don't need to love you for your power to be secure, and in fact, it's far preferable to be respected because people fear you than to be respected because people love you.
It's challenging to engage with articles quoting individuals who support crimes against humanity. Still, if we give some credit to Blinken's statement that 'China may have stopped Putin from using nuclear weapons,' it prompts an interesting question: Could someone have encouraged Putin toward using such weapons? And if so, is it possible that figures like Blinken are not entirely disconnected from this eventuality?
Crimes against humanity are among the most serious offenses, second only to genocide. Someone capable of such crimes is hypothetically capable of all vices.
