Correction: "instability caused by the US-led and demanded sanctions against Russia."

Note that #1 and #2 on your list have everything to do with the war in Ukraine. Boris Johnson was the #1 European leader pushing the US-led war against Ukraine, and the first to lose his job. Truss is rabidly anti-Russian, and it looks like she'll be gone in a few weeks.

It was two days AFTER Germany canceled Nordstream II - at US insistance - that Russia invaded Ukraine. Trump sanctioned companies building NS II. Biden promised the US would end NS II. Condi Rice noted in 2014 that the Russian/EU gas business needed to be ended.

The problem is that 30 years of globalization has made it impossible to instantly cut off a major energy and food supplier like Russia/Belarus without major problems for the end customers. Those end customers are the global south and represent well over 50% of the world's population.

The war in Ukraine is, as usual, a war over resources. The US wants to sell LNG to Europe, and Europe and Russia were getting along fine without the US with NS I, and this trade would have doubled with NS II while reducing significantly Ukraine's income from gas pipelines through their country.

This war brings no advantages for the average people of any country at great cost to those same average people.

I think we'll see more Western Ukraine war hawk leaders fail long before Putin is pushed from power.
