My source is I have eyes and ears.
As for status quo, mostly true, but despite what the American left wants people to believe, Trump commanded a lot of respect from other world leaders.
Not the "oh he's such a good guy, I want to be his friend" kind of respect, bug the "ok this guy's obnoxious, but we don't want to piss him off too much" kind of respect, which is exactly thd kind of respect a president needs to earn from guys like Putin and Winnie.
The idea of "mutually assured destruction", while insane on the face of it, was still a deterrent. I'm pretty sure neither Putin nor Winnie are remotely worried about Brandon even having enough mental faculties, let alone balls, to retaliate should they decide to launch nukes.
