For all the talk about peace and harmony, China is doing everything it can to ensure that it is contained by nations that are concerned about it. Its militarization, its aggression against its smaller neighbors, it is pushing Asia towards India and the US, not the US and India towards East Asia.
India and the US are being approached by every nation around China with the intention of bettering their ties and countering Chinese influence.
Stick to technical topics, this may not be your strong suit.
Prussia's seven year war almost destroyed it, Cao Cao during the three kingdoms was almost destroyed so many times, as was Oda nobunaga and minamoto yoritomo of Japan.
Rising powers need to carve a place in the world, nobody will give it to you and the smaller states will act against you.
The thing China has going for it is that you cannot make conquer China, you won't destroy the infrastructure we built without risking nuclear war and end of the world, and you certainly cannot take us out of the international trade community seeing as we are the biggest trade nation and not you(obviously we can't do it to you either).
In the end, China is in a much better place than the aforementioned leaders were. No matter what you do, even if in victory, you cannot do any actual damage to China's progress and thus, even if you damage it or slow it, you cannot stop it.
India with Australia, Japan, Vietnam, Sri Lanka. The US with nearly everyone except North Korea, a rising India will ensure that China never becomes a hegemon in East Asia, the US just helps make sure of it.
That's where you are wrong, India is special, it's also huge. Soon it will wonder, why the fifth fleet is the most powerful in Indian waters, why United Nations they cannot make any decisions, why America should dictate terms in its interaction with India and world wide, and why India is contributing hard cash, but has no say in IMF.
So no, India doesn't have to be on China's side, but it won't be on yours, not unless you are willing to give up power to India, which btw we all know you are not.
Japan's PM's main goal is economy, even if we shot his family he still would not go to war, not unless his party wants no part of any future government.
Australia, Vietnam, Philippines, Sri Lanka, Thailand, and more are not only your exclusive allies, but even if true, the difference between China and the US, isn't these countries and when we match you, it wouldn't matter if you have them or not.
I look forward to improved US-Indo cooperation in all manners of our relationship, not just in military, but all aspects!
cool
