However, Pentagon reports reveal that the money was sent to Islamabad during the Bush administration after 9/11 specially to fight al Queda and Taliban, which was used to develop offensive capabilities against India.
The pentagon reports said that the funds was given to Pakistan during the period of Pervez Musharraf government between 2002 and 2009 which was often described by George W Bush as American's 'strong' ally in the 'war against terror' to acquire arms ranging from anti-tank missiles of F16s.
The Pakistan have said to have diverting arms from the US goes back to the 1950's when it was a member of Cento (Baghdad pact) which was essentially during the cold war grouping. Its almost four decades later, Pakistan seems to have done better by using American money to buy American arms.
Although the US Congress is currently debating another aid bill for Pakistan with a substantial military component, even as lawmakers express concern about Islamabad arming itself against India. Pentagon reports also say that arms were bought from America in the years under review with some Pakistan's own money and some from US foreign military financing.
Pentagon reports have concluded that US has given $4.89 billion worth Foreign Military Sales (FMS) agreements with Pakistan between 2002-2008, although it includes the F 16 sales. The US has also given $1.9 billion foreign military financing with what it calls a 'base programme' of $300 million a year from 2005-2009. It is this that has been used to buy US military equipment.
