I'm glad this is over and India come to its senses, but too bad China didn't get the chance to test out their shiny hardware.
There is a few takes away from this.
1. Chinese foreign policy is being very cautious and methodical and they are not run by trigger happy armatures, this shows to the rest of the world that China is a responsible power and it does not act base on emotions.
2. Indians are not to be trusted, China never really spend too much of their focus on India in the past, it always sees India as this annoying country with a loud mouth, India on the other hand always trying to gain China's attention, now they have it, and I hope China makes India regret they did this in the first place. Further enhance relations with India's neighbors, further pull them out of India's orbit.
3. The Chinese civilian leadership is fully in control of the their military, I have no doubt during this dispute there were very strong voices in the PLA calling for war, this demonstrates a very healthily civilian/military leadership relations.
4. During this dispute no nation in the world officially came to India's side despite the very heavy lobbying of India leaders, this shows that no one wants to piss off China, not even the country that hates China and wants to contain it (US, Japan, Vietnam etc...).
5. No nation came to China's side either, so this also means China has not YET reach its full potential and became world #1, there is still room to go.
I hope China send a open message to its border troops and rest of the world that any further incursion will be dealt accordingly on the spot, they have the right to shoot at the intruders as any nations has the right to do so. If India tries this again there won't be stand out, there will just be dead bodies.
