Bullshit. Why do you think that sanctions against Russia will be permanent- or that the war between Russia and Ukraine isn't going to be concluded by then, regardless of who is President?
Further, Biden is going to be crushed if he can't get gasoline prices and inflation under control. I expect that he will look to make peace with Uncle Pooty sooner rather than later.
Lastly, the Russian Federation is by no means "fucked". They will just ship their oil and gas to Red China, Korea and other Asian powers instead. The ones who are fucked are the Germans and French- who BTW, have never apologized to Putin for invading Russia in 1941 or 1812. They are the ones who really rely on Texas Tea from Russia.
