The documents from Pentagon reveals that Pakistan has used a part of the fund of military aid from the US in building army for a conventional warfare against India. The fund was given by the US to fight terrorism in Pakistan.

According to the Pentagon documents, the use of fund for warfare against India was with the knowledge of the then Bush administration. It provided $1.9 billion in foreign military financing (FMF). It even came down to an agreement with Pak for military sales that was worth about $5 billion during the period.
The documents of the Pentagon also revealed that a good part of the post-9/11 American defence supply to Pakistan under foreign military financing had nothing to do with its fight against terrorism.
It is a fact that the Taliban and al-Qaida gained ground in the border areas of Pakistan and Afghanistan, Islamabad purchased eight P-3C Orion maritime patrol aircraft and their refurbishment that was worth $474 million. Islamabad also placed orders for 5,250 TOW anti-armour missiles that was worth $186 million.
