I think The Russia Federation underestimated much much life and money NATO was willing to waste dragging out the war in Ukraine. US figures did openly state the war is about weakening Russia, and the USA barely cares about its own people, let alone anyone in Eurasia. Maybe Russia also underestimated how weak, corrupt and sycophantic Europe leaders had become? Willing to kneecap their own economies for the US oligarchs and back a US/NATO provoked proxy war on Russia’s border for US hegemony.
