I never said they were "unscathed". They're fighting (and winning) a war! Against NATO expansion into their back yard that they warned against for decades. Neutrality for Ukraine, simple stuff. They consider it existential to their survival whether you agree with them or not! Deal with it!
They're two years into a two week campaign, how impressive.
Also, if you think this is all about NATO, then you don't know the history of Russia or the history of Ukraine particularly well. Russia's been trying to Russify Ukraine since before the United States was even a country.
