B) is already happening, just see the UNs statement a few days back.
Yeah, I saw that tripe.
We should start taking the step to leave the UN 10-15 years from now and also make sure that we have a lot of countries that follow us out while we leave. This cannot happen without a solid framework that focuses on expanding our relations, trade, and cooperation with ALL the developing countries while emphasizing our narrative into their subconscious. It needs to be communicated so well that they are able to identify their common issues with us and reach out to us more than ever.
Let's see:
The only 4 countries with whom we have tense relations (from mild irritation to downright hostile relations) are Pakistan, China, Turkey, and to some extent Bangladesh).
That leaves 191 countries, out of which, 35 are outright extensions of the United States: 26 EU member states, the UK, Japan, South Korea, Australia, Canada, Singapore, Taiwan, and New Zealand. While all these countries have excellent relations with India, they will most likely do what the US tells them to do.
The other countries apart from these also have good relations with all the big powers, they are just too small to politically do something internationally.
That leaves a good 150 countries across Africa, Southeast Asia, Central Asia, Central America, South America, the Pacific, Oceania, etc. This is where India should be flooring the accelerators and reaching out to - double down on mini-laterals such as India-Africa Summit, India-Pacific Islands Forum, India-CARICOM Summit, India-Latin America Conference, India-Central & East Europe Summit, etc.
We need to establish our narrative in the consciousness of the developing world. That is how we build our clout; through cohesive outreach, mutual benefits, and conflict resolutions in different regions.
Now coming to the diplomacy side, we are extremely understaffed in the diplomatic area. 6,500+ staff for all the countries of the world is abysmal. Even the South Koreans have more diplomatic staff than us. Jaishankar needs more lateral-entry professionals; ideally those with experience in foreign trade, contract negotiations, trade policy framework development, and project management, planning & implementation.
In short, we need a serious plan to make sure that the UN becomes useless in the coming decade, by building a narrative that connects with the very leadership of the developing world and being able to materially help them such that they are able to trust us as reliable partners.
