For what it's worth, I believe the current war in Ukraine will change things fundamentally. Navalny has indeed at different times been quoted saying things only a self absorbed Russian nationalist would believe and support, and it also no secret that Navalny had been making at least partially successful attempts to unite Russian right wing opposition and cater to their tastes. But when the war like one currently taking place in Ukraine will be lost by Russia, it will not be able to carry on in its current form as a Russian federation. When the Soviet Union fell, a good number of territories got, as a minimum, a formal independence from Moscow, and a similar sort of thing should happen after the current war. The Russian right wing understanding of what Russia is should change, and thus the likes of Navalny would have some different views as compared to what they might have been ten or more years ago.
