I am afraid, in the IAs dictionary, appropriate response == proportional response. This proportional response nonsense is like two guys slapping each others wives because they are mad at each other. Unless the IA reaches out and touches the lives of PA Colonels, Brigadiers etc. to me, this is just business as usual.
What indeed is an appropriate response? Its is one that will make the other guy stop slapping my loved ones. If a growl is needed to stop him, a growl. If a slap is needed to stop him, then a slap. If we need to break his hand to make it stop, then breaking his hand.
In fact killing even a hundred foot soldiers is so much the better for the gernails as it makes they can puff up and prance around saying we 'resisted the Indians' and therefore it was a great victory. What is needed is a humiliation that will make them lose face, that will demonstrably show to their public that their faujis are eunuchs.
Blow up some battalion or brigade hq with a precision strike. Sink some of their submarines.. Take over parts of PoK so the border is 'rationalized' in our favor.. Treat their elite as scum. Anal cavity searchs required for entry.
Apply sanctions.. That is my list. Some of it is happening, but not enough. Hope this time, Northern Command does an actual appropriate response, not proportional.
