I agree with not allowing Ukraine to join NATO, but this idea that NATO should be dissolved is a ridiculous, pro-Putin talking point. NATO is the single most successful military alliance in modern history. It was created to oppose Russian expansion, and it has been extremely successful in maintaining that goal. The idea that it's not necessary is utter nonsense that only serves Putin's desires. There's a reason why his primary behavior has been in service of weakening NATO, and spreading propaganda aimed at changing public sentiment about the alliance. Without NATO, Putin will invade one European nation after another as he works to achieve his goal of reconstituting the Soviet Union, and expanding into Europe. NATO is the essential push back on Putin's agenda, and they have been widely successful in containing him, and preventing war throughout Europe. Putin is the only one who benefits from the dissolution of NATO.
