It is obvious to everyone, which is why several key democracies around the world are funnelling billions into the only country actively fighting Russia. The US is using it's own intelligence and command functions to help guide Ukraine in what to fight and where. Russia is being overthrown and their arrogant invasion is how Putin will lose a tremendous amount of credibility worldwide.
Russian military tech has been proven to be substandard when compared to literally any other arms manufacturing nation except China and India. German, Swedish, UK, French, and US weapons are being used against Russia to incredible effect and showing other national leaders how ineffective Russian weapons are. This means far fewer nations will field Russian tech and gear.
Russian without the illusion of power will have some serious internal upsets, like the recent Wagner and rebel uprisings. Whoever replaces Putin will not renew those conservative back channels because those relationship are contingent on being an international asshole, which a new leader can't afford to be.
So don't worry about the long term effects since Russia may not be here for long. Everyone does see Russia being an international asshole and it's the reason they are losing their war.
