Actually, after reflection (and discussion with my wife) I can converge somewhat with you, Fjallstrom :

Perhaps Putin and Biden are objective allies, insofar as they are each other's useful idiots :

Biden is seen to be "standing up to a bully" and to be "proved right" about Putin's malevolent intentions. He could care less about another war in eastern Europe. No skin in the game.

Putin is delighted to stand up to Biden, to excite his population about alleged Russian greatness, and to have a little low-cost military action. He could care less about his country's economy.
