Biggest mistake India ever did was intervention in East Pakistan in 1971. Since then, this region never saw peace again. But things can still be settled down if India accepts kashmir as the part of Pakistan.
This way things will never get solved. Got to accept each other, got pardon each other. Got to respect each other.no no no ... they took OUR land so it cannot be settled by them accepting Kashmir as our's since it was/is/will be our's in the first place, the only way i will want to see it settled is to see India losing a part of it's land as well
