Definitely not ... We should build the capability but do not test unless necessary ...
Remember if we have the capability US would no and there is no point of testing... Most important is to have the capability to take care of Aircraft carrier ...
US has three options:
1) Use India, which means China involved as China cannot afford to lose the CPEC route to Indian ocean otherwise CHina will be surrounded from Malacca strait and Indian ocean
2) Afghanistan: for which they have to increase the force size but this will be very risky. First of all supply line of forces in Afghanistan is through Pakistan so sort of impossible furthermore, alot of Pushtoons still have respect for Pakistanis and in case of war against Pakistan US soldiers have to be in front and vulnerable
3) Aircraft carrier,,, this is the only weak point where they can bring two CBG into Arabian sea block our sea lanes and rain us with cruise missiles ... We have to find a away to take care of that ...
Remember for a bigger enemy far far away you have to apply anti-access and area denial and not attacking capabilities ... It will give them further reasons to have a direct attack on Pakistan which is in current scenario next to impossible ...
