That comparison does not make sense. Russia is not the USSR of old or Germany in the 30s. It's not a great economic power with an independent industrial base.

That comparison does not make sense. Russia is not the USSR of old or Germany in the 30s. It's not a great economic power with an independent industrial base. Right now, Putin is throwing in all the conventional forces he can spare, but Ukraine – a smaller and poorer country - has managed to stop the attack with some material support from the West. Meanwhile, the rest of the world has not been idle. Europe is increasing military spending significantly. Unprecedented sanctions are in place, and their purpose is to destroy Russian economy and cut their access to many key technologies. If the sanctions remain in place, a large part of the Russian losses in Ukraine will be permanent.
