Ulysses S. Grant famously used precision deep-strike weapons to eliminate Vicksburg and Jackson instead of going down the Mississippi and taking them directly. Ukraine is right to imitate him.
I wish I knew how to tell bro he's an idealist and has brain worms in real life person language. He says revolutionary governments should work to oppress the bourgeoisie, but if the vanguard party isn't abolished/dissolved/weakened within a certain amount of time its "authoritarian". I keep trying to address external pressures on these entities and what I feel like is a fundamental misunderstanding of the concept by him, but it's to no avail.
I've always said that the vanguard party isn't meant to organize some sort of higher brow tier of individual and separate them from some chafe, but to organize those with higher class and political consciousness into one group so that they might be ready when capitalism fails to solve converging crises.
