Didn't they provide new F-16s? What makes you think that they would not have provided other weapons?
Also, we could divert some resources from the Indian border for this operation.
do you really live live in Pakistan? how much do you know about military logistics and troops movement?
do you have a clue how many Infantry, mechanized infantry, armour and artillery divisions India has along the border with Pakistan? (make a guess why they are there?)
Why do you think they are there? And if Pakistan does move a substantial part of its forces defending our side against any possible Indian invasion, what guarantee do you have that the Indians will also move back their troops away from the borders? Or at least wont do anything while we leave our flanks open to them? Specially if there is a Mumbai style atrocity as well while we are busy doing the American bidding in NW?
Are you aware that Americans not only refused access to drone technology but also refused to share the command and control of their operations? Also they turned down the gunships and even the troops transport helicopters that are a must in the COIN operations, super sonic jets are not the appropriate and cost effective means to fight the insurgency.
The so called military aid was cut off ages ago F-16s were fully paid for by us, they are not part of the aid.
I am not sure how many times you had to relocate from one city to another so I dont know if you can imagine the time, money and the logistics required to move tens of thousands of troops from one side of the border to the other side where the terrain itself is not plain and easy. NW operation was never a NO NO for our army, but we have only managed to consolidate our positions throughout the Pak Afghan border excluding that part of the agency and not ignoring the BLA terrorism in Balochistan and the Swat operation when world started crying that the terrorists were 60 miles away from the capital.
The better option which Pakistan has been trying to convince the yanks is to get on the table with the Taliban which is much easier and better approach because all the might and firepower has not subdued the will of the Afghans. Pakistan has suffered a lot already and it is not in its interest to go into NW as the next demand is going to be going after the Quetta Shurah.
Given the American attitude towards Pakistani concerns re BLA and the freedom of movement of the TTP leadership in Afghanistan and facilitating our most wanted terrorist Bramdagh Bughtti, I dont think any Pakistani should be willing to sacrifice any more lives for such kind of an ally. American double games even before the invasion of Afghanistan when they established contacts with BLA as an insurance policy against Pakistan mean that they dont have any right to complain about Pakistan not launching NW operations or keeping contacts with Haqqanis although its the same veritable arm that Gen Mullens team is now meeting in Doha and Saudi Arabia.
