Sure, but propaganda works more by “licensing” than “brainwashing.” There are underlying material conditions for the conflict.
If the war kicked off because of NATO encirclement, and there are now two more NATO members than before the war… What’s the end goal?
Regardless of morals, Ukraine is being demillitarized, and Donetsk and Luhansk are being folded into Russian territory. These are 2 explicit goals of Russia’s that are hard to deny at this point. What matters more for Russia isn’t necessarily the total number of NATO countries, but their relative proximity and millitary power. Much of NATO is de-industrialized and doesn’t actually have much of a long-standing fighting force except the US. Russia is now less encircled than before, but the NATO-aligned and non-NATO aligned countries are at a higher split than before.
