"though these days I don't trust China; I am increasingly suspicious of it."
I never trust China or the ruling class government of *any* nation. I simply do not trust the U.S. government more, because I not only see its foreign policies, as you do, but I have to deal with the constant lies that underlie its domestic policies too.
"Still I feel that the current war is something different. I feel that the roles have changed and this time it is Russia (Putin's Russia) that is worse of these two. I feel that this war is more dangerous than any war for a long, long time. And I am quite sure that the US is not going to attack Europe, whereas Russia..."
Here is the thing. There is no "worse" nation here. It's purely business as usual. The U.S. government did everything in its power to provoke Russia into invading Ukraine as I explained, starting with getting the latter to lie and say they were joining NATO and getting the new puppet government to bomb the Donbas region, which is filled with Russian-speaking people who largely identify, nationally, with Russia rather than Ukraine.
This is because the U.S. wants Russia weakened due to the now destroyed pipeline it was using to sell cheap liquefied gas to European nations and its working with China and Saudi Arabia to create an alternate form of international currency outside the U.S. petrodollar. The same thing regarding Taiwan.
This war is indeed more dangerous than any before, because it involves the U.S. antagonizing and harassing two nuclear armed nations. If the U.S. would allow Ukraine to negotiate with Russia about Donbas and stop feeding into the war profiteering needs of the military industrial complex, Russia would have no need to invade any European nation. That would be a big undertaking for Russia, and it would be appeased if its government was simply allowed to do business as usual with selling cheap gas. But the U.S. doesn't want that for reasons related to business.
The U.S. may not want to literally invade Europe militarily, but it *does* want to control it in ways that are very destructive to the people living there. For one thing, it wants pretty much every European nation to join NATO, thus making them indebted to the U.S. military industrial complex by forcing them to purchase very expensive weapons from the U.S. and to engage in acts of aggression against Russia and elsewhere on behalf of U.S. business interests.
The bombing of the Nordstrom 2 pipeline caused many nations in Europe, particularly Germany, to suffer a major loss of needed gas for heating in the winter, with the ultimate goal that its government instead spends far more money to purchase this resource from the U.S. And this proxy war on Russia via Ukraine is not only causing numerous needless casualties on the Ukrainian people and Russian soldiers, but if a nuclear war happens, you can rest assured that Europe, along with the rest of the world, will be thoroughly fucked in ways you do not want to think about. And you can thank the U.S. government for that. They are not heroes trying to do the right thing for the sake of doing the right thing. It's all for the benefit of American plutocrats, and no one else, least of all European citizens.
Btw, your English is entirely coherent, my friend. Worry not about that!
