I do agree that most people in India do feel China as a threat because its portrayed to be so. And yes to a certain extent true also.
See, apart from some borer skrimishes I dont see a full fledged war happening in future also.
See we have to look at two scenarios over here...
The real war and the proxy war.
Currently every country in the planet is fighting a proxy war with someone or other where strategic and personal interests are involved.
1. India and pakistan in proxy war.
2. China and India - some border issues and kind of proxy war....
3. US-China, US-Russia proxy war.
4. US and North Korea proxy war....
though the proxy war word is quite debatable here, what iam refering to is a scenario where every country on the 4 points mentioned above consider each other a threat.....
So its quite logical to think that if any of these 2 countries mentioned above go to a war ever?, then its a win for the other 2 countries...and the interesting fact is that every country knows it....
we are stitting on a politicaly, economically, and militarily the hottest bed on thsi planet, which is south east Asia, not to mention its strategic ties and influences on middle east.....
If any of these countries go to war, imagine how big the situation will be when every planner in the coutry knows that its quite volatile.....
i wont go to details.....Gone are those days when you will say China is a threat to India, today if China wants to take Arunachal pradesh by force, the retaliation from Indian side will be massive and "might" lead to a full scale war, which none of the countries can afford now....
