And like you say freedom of movement and access to more non military help.Hmmm not sure what the immediate benefit might be . There is always the general benefit of being in a block, closer ties, borderless travel (helps refugees?), free tradeā¦ no obvious security benefits yet. As you say NATO is a separate entityā¦
Pure speculation, but Putin is demanding at the peace talks that Ukraine is neutral. Maybe Zelensky is getting ahead of that - itās easier for Putin to put a stop to something before it ever happens than if the wheels are already in motion.
