Many people seem to assume that democratization of Russia will solve the main problem, which is Russian imperialism and expansionism. The immediate aim is to support Ukraine in its struggle to free itself from Russian occupation and agression through military action by supplying the physical means and resources to do so. Whether Russia becomes democratic as an outcome or through the workings of these actions is irrelevant from the standpoint of the grand strategic aim of winning the war.
I don’t think there is necessarily a need for an “internal drive” toward democracy. The current mindset of the majority of Ukrainians proves the point. Ukrainians have pretty consistently sought national self-determination throughout their history, regardless of the form of government or constitution. They were resigned to live under Russian hegemony since at least the early 19th century. The turnabout started in 1991, before which there was no more a history or tradition of Ukrainian democracy than in Russia or any of the other Soviet satrapies.
If the Ukrainian people can change their mindset in the space of 30 years then, so can the Russians. But that should give us an idea of the time that is needed to effect the transition.
The Japanese, Germans and Italians adopted democracy after WWII as a result of total defeat and humiliation. The likelihood that Russia will be in such abject straights at the end of the current war is, for all intents and purposes, nil.
Russia is currently deterred from further escalation by NATO and, especially, the US nuclear umbrella and material support to Ukraine. The Ukrainians are training and preparing for a long-term struggle and, even more significant, the need to continue deterring Russia post-liberation of their country.
We in the West and NATO must accept that whatever the immediate outcome in Ukraine, Russia (and its dubious allies) will have to be contained and deterred for the foreseeable future. And that’s regardless of what happens to Putin and his henchmen.
