Looking from the outside, the US was already losing its focus and leading into ideological/tribal thinking with the Viet Nam war and the fight over Afghanistan. By the time the USSR fell, the US was heavily entrenched in tribal manifest destiny, and no longer focused on progress or willing to learn from what other nations were doing well.

Russia, in contrast, was quickly captured by the soviet power mongers without the traditional trappings of the communist government to keep them at least partially in check. So they gathered their oligarchs and went full on tribal mafia.

The US eventually picked China to be the new target of hate, but China was more canny and used that window to buy all the production and delivery out from under the US, and then went on to buy a lot of the land and companies within the US. As a result, the US government could only push Chinese hatred so far.

And then Russia succeeded in working with rich Americans to get the oligarch class installed in the US as well, so there were people in power with shared interests.

It all happened out in the open and shouldn’t be a surprise; there were even people warning about the likely result every step of the way.
