@chinapakistan : indian ocean and all the others belong to everyone yet there is something called "strategic defence".
Yet to be deployed ins Arihant is causing trouble to pakistan which is no where close to pakistan, 3 years away frm launch.
So friend why wont a country having NFU POLICY be troubld when a nuclear sub belonging to a country with which we already had wars and have disputes over land , enters in waters close to our shores?
Plz tell me will this concern of our navy differ in case of pakistan navy or chinese nayy if ins arihant says hullo from 1 mile away nar ur territory lying in international waters,
with 4 certain carriers by 2025, 6 nuclear subs , u212/214 in pipelin ,P8s coming and 40 other ships under construction indian navy will be certainly a undisputed king of the region.
