In the sense that Europe, NATO, and the US were involved in the politics prior to this war starting, yes. Biden's response to Russian moves was indecisive, in Russian eyes, irrelevant, and generally fucked up. But that's Biden. He's been wrong on foreign policy almost 100% of the time for nearly half-a-century. So, yes, this war in good part is Biden's fault for being the retard he always has been.
Europe on the other hand, showed nothing but weakness. There was no resolve and every desire for the problem to just go away. That's nothing new for Europe. Putin read their weakness, and Biden's indecisiveness and lack of commitment as a green light to invade Ukraine.
