UN will have little more than “talk” and diplomatic stands opposing what Putins doing.....Putins military being there has secured Ukraine regardless if anyone likes what he’s doing or not. UN leaders know this....they just need to quiet the nations people and make it clear to Putin not to overplay his hand.
Additionally, Putin is going to protect his ports and access to the Mediterraninan....we would do likewise in his place.
Nobody’s going to disrupt the flow of oil...and the UN will pretty much bend some concerning what Putin ultimately requests....he’s in a game of poker now.
UN is useless, why even bother with them.
