I have been thinking about this a lot lately. If you look at effects of geopolitical events and who profits and loses, rather than stated intentions. This global oil crisis, the Ukraine crisis, tariffs ect. It's the equivalent of the "the purpose of the system is what it does".

Oil crisis: Trumps friends profit on insider info, US oil industry (also his friends) profits, Russia profits because they are another big oil producer, USD dominance is harmed (also helps Russia), everyone else in the world eats the costs

Ukraine: Russia bleeds, Ukraine bleeds, arms industry profits, politicians in general get something to grandstand on in front of the voters. Personally I believe that this conflict has been artificially prolonged just to amplify the effects

Tariffs: US public eats the costs, Trump profits politically by appearing strong, Trumps friends profit on insider info
