As someone else pointed out above - this is going to be a surprising century for y'all promurica folks. Or for the the posterity, at least. Won't even be China to be blamed. Might not even be a state. Not seeing where this train is headed (and not just with the AI) - this is the biggest issue with the overall comprehension of the larger picture. But opening your eyes and learning to make sense of the world around isn't something you can learn by being lectured on HN, unfortunately.
It's a soothing feeling to have, though - this belief you're on the "good guys" team. Comfy. Also helps when you're arguing, doesn't it? OR when your passport allows you to travel to more places. Very nice indeed, but not a single a thought is usually given as to why, say, the latter, is the case. "Ignorance is our only ammunition".
DISCLAIMER: I DO NOT hate America. It's given this world a lot of good things and personally affected my life through art, books, movies, music, language and other things. I used to visit, but I think I could've never enjoyed living there. I used to think it's the American movies that perpetrate lies about how life really is, but then when you see it, you realize the lies is anywhere but in the movies (even the bad ones). Lies not by the people... Just lies. Fake. Vanity. Madness. And the only true thing I found in America was my one and only love. For which I'm forever grateful.
The previous - and very possibly future - President openly espoused Putin-friendly propaganda and threatened to leave NATO. European dependence on American power worked for many decades, but may leave them in a very tough situation now.
If Trump really is Putin-friendly, then Putin made a massive mistake by delaying his major military actions in Ukraine until Biden was in office.
I have no real proof of this but I suspect if Putin did delay his actions until Trump was out of office, it was because Trump was such a wild card that Putin might think that he could try to nuke the Kremlin if he didn't like what was going on in ukraine.
Disease killed more people on the frontlines in WW1 then weapons did, and it is the foolish military planner who doesn't try to avoid it (the Russian lines are currently dealing with an outbreak of Cholera in parts, which is another problem partly as a result of training quality - effective military's drill field hygiene practices because it's a direct contributor to combat effectiveness).
EDIT: i.e. when there's a novel respiratory virus about, nothing will destroy your military faster then massing for an invasion in one place.
