No, you've swallowed the Globalist/Neocon propaganda. Look at the areas Putin is claiming. They are overwhelmingly Russian. The people in those areas are not going to fight the Russians coming in. They welcome them with open arms. If Putin were out to conquer and absorb all of Ukraine why has he offered terms that he has? The claim that he wants this or that this would be his future aim are impossible to support based on the terms he is offering.
Look what percentage of GDP Finland has spent on Defense on an annual basis since WWII. They are not armed to the teeth. Far from it. They've been neutral for over 75 years. They're just fine. Same goes for Austria. The same could go for Ukraine under the terms being offered. Russia is not proposing to rule over ethnic Ukrainians who are Ukrainian speakers. If they were, then I could see your argument, but they're not.
Sure tell the dead Ukrainian's and the ones who find themselves under Putin's police state with destroyed homes, they should be glad they avoided Globalism.
