The Economist has calculated that if the Russian offensive continues at its current pace, Russia would need until June 2030 to completely occupy Ukraine's Luhansk, Donetsk, Kherson and Zaporizhzhia oblasts, and it would take another 103 years to capture the whole of Ukraine.
I am not saying things aren’t at a critical, difficult point for Ukraine, but in WW2 Russians at least had proper armor and artillery support. The T-34 was a competitive tank for most of the war and Russia had artillery support it could protect.
This is just mass slaughter, it is not the same. This is disgusting, wrong and futile. Ukraine is not more brute force strong than Russia but Ukraine can still functionally conduct armored maneuver unlike Russia.
Ukraine will crush Russia longterm, the longer Russia waits to seriously negotiate the more they lose.
