A superlative point, sir. With just two minor flaws:
(1) Ukraine are not fighting the USSR they are fighting the Russian Federation, an entity often referred too interchangeably with the former, however one with a significantly smaller population and armed forces. An accurate metric for this scenario is "You have 133 men, I have 400 men, you lose 10 men, I lose 30+ men, who is winning?", and the answer is Ukraine, Ukraine are winning the war of attrition.

Now I realise that technically speaking that's only one flaw but I thought that it was such a big one that it was worth mentioning twice.
