Smash, I see your point but based on the same logic there is a civil war in Iraq. Do you want india to run into civil war? I'd rather stick to democracy even if it has it's own flaws like the ones in india, we are at least not killing each other daily. I know there were some cases of religious killings but relatively speaking it's a lot better than some of the other countries.
Look at history, no country succeeded with force.
Economic growth is going to resolve a lot of these issue than wars/fights.
Btw, i am no way suggesting that we should not do anything when the terrorists strike. We should certainly strike back with full force. We have a wonderful defense dept to handle that.
