Oh boy. Only have time for a top three, so in no particular order:
Who considered the Russian Federation a bigger opponent than the PRC?
... Literally everyone. China was aligned as a 'follower' of the Russian Federation's geopolitical lead prior to russia's utter stomping in Ukraine. Was it incorrect? Well, obviously. But the image of the great russian bear was the specter keeping the western world up at night.
Looked in a mirror lately? The US just elected Trump
A blatant whatabboutism but just to address it: The US will be fine (diminished geopolitcally no doubt, but still in a powerful position) after this all gets sorted out internally. We survived the last trump admin, we'll come through this one too. This just isn't the fall of the roman empire like oh so many people are claiming, politically it just doesn't even resemble it.
building hospitals and infrastructure for developing and middle-income countries - the things we won’t even build domestically.
I... what? We opened half a dozen hospitals in my state alone last year. Additionally, you know the US has been the world's largest source of charity and investment in developing nations for decades, right? Look you're repeating lines from some seriously anti-china propaganda here and it's a little weird. You know about trump canceling USAID and why that's bad, right?
There's lots of things to criticize the US on (and it's something I do all the time, lets be clear) but you clearly don't know what you're talking about.
(Okay, honorable mention because I just can't with this shit:)
when it’s the reason we can’t have things like free healthcare or higher education.
The reason we don't have healthcare is fascism, not "military spending taking all the money". We could 100% have free uni and healthcare without reducing a cent to the pentagon's budget. In many states we even have (limited) free healthcare, entirely funded by state budgets. You're just repeating bullshit right-wing talking points like they're objective truth, but with a lefty spin on them.
