You don't need to be a principled Marxist to realize that people who hate you and want to destroy you are not your friends. The war made it crystal clear to the Russians that the west is their enemy and that it is an existential threat to Russia. Meanwhile, China has shown itself to be a good and reliable partner.

It's important to understand the bourgeoisie class is not homogeneous. The type of capitalists who are pro western are the ones who were benefiting from western business relations. The west, in its infinite wisdom, made sure that these people lost their assets in the west and had their businesses ruined. They got replaced by domestic bourgeoisie who filled the niches left by western companies. From their perspective, the west is just competition that needs to be kept out.

At the end of the day, China and Russia share a lot of common interests and common threats. This creates a solid basis for cooperation. On top of that, Russia and China complement each other economically. Russia has a low population density and abundant natural resources, while China has a lot of high tech industry. It's a relationship that's very similar to US and Canada incidentally.

While Russia has always had people who looked up to the west and felt some sort of inferiority, they've now either fled to the west or been ejected from politics.

It's also important to note that Putin is a moderate in Russia. Most of the other prominent politicians are far more hardline than he is, and more hostile to the west.

You are correct that there are independently minded Europeans who would want to restore relations with Russia. Hungary and Slovakia are obvious examples. However, this isn't going to be Russia getting integrated back in the west. Rather, the opposite will happen with western countries peeling off from the west to join BRICS.
