Once you add in what other allies and Ukraine itself has spent, Russia is spending far less money in Ukraine than Ukraine and its allies are.

It's also important to remember that Ukraine's pre war GDP was about $150 to $200 billion dollars, and now their economy has been almost entirely mobilized toward the war effort, which is still significant even after a 30% reduction in Ukraine's GDP. The Ukraine is essentially a NATO military base at this point and the best funded on the planet.

With the economy of Russia returning to growth, this year, the idea that Russia is "collapsing" or being brought down by this conflict is a farce being thrust upon the people in the West to give them the illusion that they're winning in some way by supporting Kyiv.
