We are all flawed, ok?

I'm very invested in this conflict for various reasons, including personal ones too. I may loose my cool to easily.

Anyways, there are great materials about this conflict in Polish. Because Poles are much more invested in that conflict for obvious reasons. There are amazing talks with experts (not mainstream media experts) which explain the geopolitical situation, that USA vs Russia is just a warmup for USA vs China. I wish I could translate those, but this is beyond my strength and schedule.
Basically Russia, Central and Eastern Europe are in very important place geopolitically in USA vs China. America wants to win this conflict by applying stranglehold on China's economy - because they import a lot of food, a lot of energy sources. America has or aims for many important alliances in the seas: Japan, South Korea, India, Australia etc etc. Currently much of China's imported oil goes something along those line:
China is also trade giant. Because naval trade has much, much, much greater capability than train or trucks, their exports also goes there.
Russia could provide China with energy. However, right now they sell oil to china from different raw material base and they can't just take all monstrous amounts of oil that EU uses and send it to China, because it takes new infrastructure. New infrastructure takes years, etc etc.
Chines aren't stupid. They saw that comming, so they launched new initiative: New Silk Road, or Belt and Road Initiative. It is supply chain optimization, so trains can go in more effective way through many countries, less delays etc etc. And look where it goes:
Through Russia, through Belarus, through Ukraine, through Poland. There is also branch though Turkey, but they invested less in it, because well it is middle east, so there might be war there (ironic to think about it today

).
Moral of the story: US can't give up on Russia or Central and Eastern Europe if US wants to fight with China.
