The two-year war in northern Ethiopia resulted in approximately 100,200 deaths before an African Union-brokered ceasefire was reached in November 2021, a new report reveals. In comparison, the Ukraine-Russia war that began in February led to 81,500 deaths, the same source added.
Because of history: Hitler started in the same way attacking Poland, and also Stalin did the same from the East (started with Poland too, and then proceeded to try to take Finland).
Stalin was fighting Nazis same as Putin though.
I recommend you to review your sources: before the start of the WWII, Stalin and Hitler signed an agreement so each could invade their own countries without interfering each other (Molotov-Ribbentrop Pact). Both sides were doing the same thing from each their side until Hitler broke the Pact by trying to invade Russia. Only then Stalin begun fighting the nazis as you claim.

Edit: to add a last phrase to conclude my argument.
I love how you shills always bring this up without mentioning the Four-Power Pact because you’re utterly intellectually dishonest https://en.wikipedia.org/wiki/Four-Power_Pact
USSR was asking for an alliance with western powers against the nazis, and all the western powers ignored that and made peace pacts with the nazis instead. US companies even continued to do business with the nazis well into the war. The IBM famously enabled the holocaust.
