On one hand it was a wise and pragmatic move by PNS to let the enemy sub go...just shooed it away.
Pak is not interested in any stupid war at all. Economy is just about to take off. So, this move makes total sense.
However, had PNS captured this sub and forced it to dock at PNS naval base.. Pak could have extracted something meaniful from this provocation.
In a way a wasted opportunity in one sense... the crew could have been released after sometime and the sub could have formed a good study plus a museum peace.
Anyhow, happy that there is no loss of life on either side.
Next time PNS must act more resolutely.
The enemy sub was there because of Sino-Pak joint naval excercise. There should be zero tolerance for such silly acts.
