OK alright, Lets see how good Policing Indian Navy can do in Somali waters. wish you best of Luck.In the previous case they were pirates, but unfortunately the Navy did not realize that the boat was not a pirate vessel, but a trawler which was hijacked by pirates (it seems that it was not possible to make that distinction because the pirates used fishing trawlers as well)
Keeping piracy in control is vital for the Indian economy, because those shipping lanes are used by the majority of ships heading for Indian ports. It would be a big blow to India if those waters were considered unsafe.
There is a difference between "invaders" and "infiltrators". The latter is tackled by the coast-guard, the former by the navy.
