International waters is totally different story, you cannot simply say that everything is an allegation and that Pakistan is not involved as there will be ton's of proof, like the Ships coordinates, GPS data etc. It won't be like Kashmir, Mumbai etc..
And you Navy is not gonna do anything in international waters. You know why ??
We are still using the same shipping channels to traverse through
strait of hormuz and beyond, the same path that will be followed to reach Chabhar. And you know what, no Pakistan Navy vessel has ever came near or harassed any Indian merchant vessel in this region yet. So enough of chest thumbing and trying to be a paper Tiger. Pakistan Navy doesn't have enough balls for that. LOL
