agreed pakistan is small and doesn't extend much beyond gujarat. But with changing situations, we have to be ready for long distance wars. Pakistan is building a gwadar port, which is 200 miles from persian gulf. What is they block ships carrying oil for us. Only an aircraft carrier can travel that far and give a devastating blow. Apart from sheer geography, we should also keep in mind, that as India is growing and becoming a super power, it needs to assert itself over long distances.
