Ukraine will prevail.
People are not snatched off the streets in Russia, unlike in Ukraine. Putin is the elected president of Russia, while the Zelensky regime is a de facto and de jure dictatorship (by now).
> How many Russians have fled their oppressive regime since the invasion began?
Obviously, the Russian population has not halved as in Ukraine, so what are you even talking about?
> How much economic activity has been lost with the West?
A lot, but that's harming the West (EU) far more than Russia. The EU economies are de facto in recession, while the Russian economy is growing (on average in recent years).
> How much military equipment has been burned up?
A lot, but Russia is outproducing the West in nearly all military metrics, quantitatively as well as qualitatively. Ukraine does not have any air defense left by now, because the West can't provide any. That's why cities like Kiev, Odessa, Kharkov, etc. are successfully targeted on a daily basis.
> Russia had to turn to China and North Korea for help.
Not really, North Korea takes its chance to gain experience in warfare, training soldiers and testing its weapons. It's a rational thing to do from the perspective of North Korea, both sides gain a lot by this.
