Not really, as you argue without respect to the core of the problem, that is, the US is building a geopolitical tool next to Russia's borders (obviously against Russia). Even if Putin suddenly disappears, another politician will get support from Russia's elite and probably easy consent from the Russian public to pursue an anti-NATO foreign policy.
Nothing will change until the US will change it's foreign policy towards Russia and stop meddling with countries bordering with Russia.
Also this does not contradict that Russia is not an oligarchy or Putin is not a dictator, before you call me pro-Putin. Russia can be the aggressor, an "extreme right-wing dictator ship" that attacked Ukraine and at the same time Ukraine was set up like a red flag in front of a bull by the West.
Remember, there is no reason a country like Russia should perceive the US and its vassal states as friendly. They have no way to assume whatever they do with Ukraine or try to do with Belarus is not against them. In fact, the opposite is true, the foreign policy of the US writes that Russia is their enemy and they will allocate so and so much funds to fight it. You think you need to be a right-wing dictator or an ex-KGB agent to grasp that the goal of the west is to subdue your political class or to turn your country into a gas colony for them?
But of course, being a biased lib that thinks the world is built like Lord of the Rings or a comic book, what's class consciousness to you? You believe that there are ebil people like Putin, that suddenly went crazy and decided to invade Ukraine for no reason than being evil.
Don't you think if the Russian capitalists are investing so much money into the war because they see Ukraine as a pawn of the US and as a threat? And they will continue fund it if it stays a threat to them, beyond Putin? Nah, they put in billions for the lolz. Because Putin said so.
