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.
At this point there’s a lot more evidence to suggest that it’s the west headed for an economic crash than Russia.
I know some well-known evidence like the mass shift towards Socialism even when Western European diaspora receive indoctrination that Socialism means command economy or absolute authority by one people instead of the original meaning of government by working class. Ironically, the USA secretly the original meaning of Socialism as a typical criteria to decide whether a country is Socialist despite the different definition of Socialism that they provided. The mass distrust towards Pax Americana, dependancy on the Western European diaspora oligarch, and authoritarian approach to international relations are more obvious hints of the demise of Pax Americana.
