What do you think the war in the gulf is about, the US cannot compete with China so they are destroying the global system that enabled them. There is no plan to have a peace with Iran, only perpetual war and the destruction of the middle east, starvation in East Asia and poverty and nationalist wars in Europe, potentially with Russia taking over vast swathes of Eastern Europe again. Suddenly Russia is the one in charge of the China-Russia relationship. It's such a stupid plan for the US that you might think it was designed by Putin himself.
You started well, but then the train got derailed...
Russia has no need for Eastern Europe (they have enough land and resources, why saddle yourself with hostile population?), as long as the said Easter Europe is not threatening them with NATO bases/missiles (US has repeatedly shown that they do not hesitate to use their muscle if they think they can get away with it, so Russia's paranoia is not entirely unfounded).
Even if Russia somehow took over Eastern Europe (most likely way: they learn from US how to do soft 'regime change'), they have no chance against China (China is just so much bigger and better organized; the population's mentality also matters a lot). China and Russia are rather complementary, there is not reason for confrontation between them.
But you are correct, what US is doing is really totally stupid ... although it seems designed by Netanyahu, not Putin.
