India’s economy is projected to reach the #3 spot by 2020 (by at least some analysts and metrics; it’s already there by PPP), surpassing Japan, and trailing only China (#1) and the US (#2). In view of China’s recent economic troubles and suspicious accounting, China’s ascent is in doubt, but India’s upward path seems more certain (say, by 2030), as its excesses have been smaller so far.
Of course, India’s economy must become more robust and structurally sound, while the legal system must strengthen as well, and corruption must be addressed. Going forward, India has huge potential due to its large population, a long-standing tradition of democracy and stable government system with non-violent transitions, convenient location for trade, proximity to major oil exporters, decent standing in the world, a large English-speaking population, massive engineering education that is gradually improving in quality, and a system of R&D institutions.
India’s military is ranked #4 in 2015 by Global Firepower after the US, Russia, and China, and followed by the UK. While this is unlikely to change by 2020, I expect Russia to drop out from the top three in 10-20 years, due to the effects of protracted financial crisis, economic stagnation, and deteriorating demographics. In contrast, both India and the UK are primed to significantly increase their military strength by 2025. With two new super-carriers, the UK will have a stronger Navy (currently, UK’s Navy is considered slightly weaker than India’s). The recently-announced massive new purchase program for strike aircraft can make the UK Air Force stronger as well (it is currently considered weaker than India’s, and is a lot smaller).
India’s initial bet on Russian fifth-gen fighters (PAK FA) has gone sour. The supersonic cruise missile Brahmos jointly developed by India and Russia hasn’t been deployed by Russia for some reason (despite its availability) and does not have direct analogues in NATO countries, while NATO can technically develop one. This raises doubts about the operational effectiveness of this primarily anti-ship missile.
Even today, India cannot project power away from its borders nearly as efficiently as the UK can (due to UK’s bases and close defense relations with NATO). And India has no military alliences like NATO and the Five Eyes. India is likely to remain the #4 military power through 2030, but if Russia is replaced by the UK in the top three, this can increase India’s significance because the UK is a part of the already-strong NATO. It’s really hard to guess the military developments by 2050, but the NATO militaries will clearly become increasingly unmanned, negating population handicaps and leveraging new technology, while other countries are likely to lag behind. The extent of this trend will be determined by specific technology developments and economic health of the countries involved.
The big diplomatic prize would be an enhanced status in the UN. India is arguing for a permanent seat in the UN Security Council, but any UN SC reform looks impossible in the next five years. Some changes may become realistic by 2025, especially after major political upheavals that some experts predict for this timeframe. A UN reform is looking more likely by 2050, especially if 20 years pass without major conflicts. Here, the key for India is to wisely navigate between other world powers, make good bets, and avoid major pitfalls, while contributing to the world peace in essential and unique ways. The current conflict with Pakistan is a serious shackle, as it confines India to the status of a regional power and limits India’s support among Muslim nations (India’s collaboration with Israel on defense matters is another issue for Muslim nations).
The rule of three. I’d like to postulate that there can be at most three global superpowers on this planet (with more comparable powers, each will hold too little sway to count as a superpower).
There is little doubt that the US will remain a superpower, even if China’s economy becomes larger. As of 2025, the EU will likely become the second global superpower, and some may argue that it already is (the EU economy is currently larger than the US economy, the EU definitely has global political, diplomatic, and economy-related reach, while enjoying two seats on the UN Security Council, etc).
So, will China or India be our next global superpower? Or neither, after all?
