The sad thing is that no matter how dire circumstances become for Russian forces, they'll still ultimately prevail due to Western spinelessness. Western GDP numbers are irrelevant when the neofascist US Republican Party is now blocking all aid to Ukraine and Orban is likewise blocking aid from the EU. Putin's greatest strength is our system of representative democracy in which ignorant stupid people get to elect cynical stupid politicians who are utterly incapable of grasping, never mind standing up to, existential threats. Our own turn to experience mass death and destruction is rapidly approaching, just as it was in the 1930s, and for the same reasons.
