Early in the Bush administration, at least, there was continuing approchement. Bush was mocked for saying something like "I looked into his [Putin's] eyes, and I trust him". I don't remember enough about the early GWOT days to pinpoint the particulars of the falling out, but I do remember thinking that there were areas of cooperation not being pursued. Like, could Russia have been brought along into Afghanistan? I thought that at the time, though I'm not sure how it looks 25 years later. Like you, however, I doubt that Russia's eventual (and justified, mind you!) current stance and status was written into stone.

> Like, could Russia have been brought along into Afghanistan?

It pretty much was. Afghanistan was a UN-sanctioned war, and Russia did not object to it from its position on the UNSC - and provided support for the invasion.

Iraq (Three permanent UNSC members voted against it), on the other hand, was a clear indication that the rules-based world is a sham and a scam... And that the only rule that matters is 'Fuck you, make me.'

You know how Trump is criticized for pursuing idiotic short-term gains that torpedo long-term trust and legitimacy? That was also the real, lasting legacy of Bush II's first term. Anyone playing by the rules is a fool.
