Yeah so the reason Trump is allying with Russia isn't because he's Putin's dog. Allying with Russia is a purely geostrategic decision meant to undermine BRICS which is the primary economic organization weakening American hegemony. The blue side of the American ruling class first aligned with the European bloc which sought to destroy or at least severely weaken Russia through the Ukraine war and economic sanctions partly because of the threat Russia could be militarily but mainly because of the threat to western global economic institutions like the IMF and World Bank that BRICS poses. Russian economic presence in Africa and West Asia is a direct threat to the imperial core's ability to extract wealth from those regions. They do not wish to have competition, their economies can't honestly survive that competition long term. This route is very obviously failing. Russia still exists, it is still economically strong, weakened a bit yeah but not unrecoverable. Europe isn't though, Europe is pushing austerity on its people to fund a military build up.

The red side of the American ruling class recognizes this failure and is taking a different route. It seeks to make an ally of Russia in order to isolate China and, ideally, create a new economic bloc with Russia to exploit the imperial periphery and make a semi-periphery of Europe.

Personally I do not believe this route will work either but I do believe it is what they are hoping for. Entire nations do not decide their broad geopolitical decisions based on personal relationship.
