Do you think NATO as a system of US-led collective security for Europe is relevant in an increasingly multipolar world? Justify your answer.

NATO, North Atlantic Treaty Organization, is US-led collective security architecture of cold war era to deter rising communist trend in primarily Europe. It's continued existence in today's multipolar world having mixed reaction. Relevance of NATO: 1) Increasingly multipolar world: Polarity dilemma and rising powers like Russia, China 2) Declining US and Western hegemony: Resulting into conflict like Russia-Ukraine war 3) Small nations can't defend themselves against superpowers (Finland - Joining NATO, 3rd country joined collective might against aggressor like Russia, China it required 4) Collective human against aggressor like Russia, China it required 5) Nuclear deterrence:

Ensuring cold war remains cold and today no nuclear escalation. But emphasis should be on collective security architecture promoted by United Nations Security Council: 1) Against aggressor and not against particular country 2) Ensuring global peace and stability 3) Ensuring 3rd world war doesn't happen 4) "This is not era of war, but era of dialogue and diplomacy" - PM Modi Way Forward: 1) UNSC reforms as per present geopolitical power realities 2) Economic sanctions against aggressor disturbing global peace 3) Dismantling collective defence institutes like NATO 4) Rule based international order, led by United Nations. Then only conflicts like Russia-Ukraine war won't happen in future
