That is what people said when NATO was first coined but democratic countries still got on board and as years passed more countries who never had a dispute with the Soviet Union realized its potential and joined. Rest is history Soviet Union became Russia. Likewise, Einsteins like you can say whatever that helps them sleep at night but sooner or later QUAD with a security framework is destined to happen. The more radically PRC behaves the sooner it'll get finalized.Since falling short of proper IQ you cannot comprehend why an Asian NATO will never happen. The legitimacy of QUAD itself is questionable from the start. Japan and India have territorial dispute with China, Australia does not fit in this picture now does it? It only joined because of the pressure from the US. Vietnam and Philippines do meet this requirement but will never be part of this security alliance for a number of reasons. 1. A communist country? Seriously? Absolutely a no go area. 2. Philippines is separated by sea, are you expecting Ph Navy to make any difference in a sea battle against the most powerful Naval force in the region? Even the Japanese Navy is wetting its pants. Also don't expect the Japanese to be that serious about the QUAD thing, we know the Japs were also forced into this by its master. In the case of Taiwan it is more about being invaded rather than territorial issue but still not invited to join, because that would provoke China to an immediate escalation. Even US is not that stupid to go this far. NATO was created out of fear for a land invasion by Russia throughout Europe which is mostly connected by land. Taiwan is the only one who fears for an invasion while the rest of the neighboring countries don't share that fear, hence the QUAD started with only this tiny number of membership and will remain that small or will eventually disintegrate.
