I don't see why Pakistan is making such a big deal over this issues, I mean (no offence) but Pakistan can't hope to be able to defend itself for more than a small period against the much larger and better equipped Indian armed forces can they?
Pakistan still sees itself as India's equal when the truth is they haven't been India's equal for one moment in Pakistan's 60yr existence. Even in 1947 India was much larger with a much larger army.
Pakistan is going to complain to whoever's listening (in this case the US as they need Pakistan to control elements THEY created in AFGHANISTAN) it's just like a child throwing their toys out a pram.
