hmmm..But in kargil war, you forgot one important point.. The pakis were worried about the fuel depots in karachi even though it is thousands of miles away from kargil.Why? because Indian navy was planning to block karachi port. When nawaz saw this danger, he rushed to washington. so what I want to convey is battle can be opened in any sector but once started.. there are various modes of neutralizing enemy apart from direct fight on the battle field..
