Let's look at the Russian strategic objectives first... Russia is seeking to get Europe and the United States to buy into the notion of a negotiated new European security framework. It's something that Russia put on the table prior to invading Ukraine. If people remember back to Dec. 17, I believe, of last year, Russia submitted two draft treaties, one to NATO, one to the United States, which articulated Russia's stance on what its vision of a new European security framework could look like. They invited the West to read it and have a serious discussion about it, and they were ignored.
Then Russia invaded Ukraine, and Russia has two objectives. One is the demilitarization of Ukraine, the other is the deNazification of Ukraine. Demilitarization means the elimination of all NATO influence on the Ukrainian military, and deNazification means just that, getting rid of everything that Russia considers to be related to the ultra nationalistic ideology of Stepan Bandera and the white supremacist manifestations of that.
