"Russians now sell a lot of oil to India for rupees (and note that there does not seem to be any initiative to bomb India for engaging in this trade), but then are basically forced to use those same rupees to buy stuff from India again".
That is how the world economy used to work, before the petrodollar.
Now, Saudis or Qatar or pick your favorite Middle eastern monarch sell oil to US and everyone else in exchange for $USD. Since oil is used in nearly every other product line, either for transport or actual product, now world trade depends on how much $USD you have to buy said oil.
Euro is irrelevant outside of Europe.
"I speak German and I can guarantee you that American military presence has approximately zero influence on German politics."
Then why the fuck did they put sanctions on Russia? Why the fuck did they agree to buy a much more expensive liquid gas from the US when they had a cheaper alternative that allowed them to have such a great economy? And why did they not react when Nord Stream pipelines, the source of that cheap gas, got blown up?
What, they just sucked it up and said "hell, it's worth it, at least Russia is bad!"?
They tanked their own economy because Uncle Sam told them to do so, and not a single rational decision has ever been made by the German government since February 2022.
You can't argue with "the truth" here. Global warming has been a mainstream scarecrow for decades now.
In truth, it was just a way to slow down the growth of rival industrialized countries, or countries that are yet to industrialize. By promoting expensive, inefficient "clean" energy sources (but not nuclear!), they are stunting the growth of developing nations.
