> My guess would be because Pakistan has had good relations with US since it's independence. More often not. There was a period from the 1970s when Pakistan was embargoed because of its nuclear power + weapons programmes, mainly in cooperation with France. This pushed Pakistan into the Chinese camp for arms supplies where they have remained firmly lodged ever since. During the 1980s the USA did supply some silver-bullet assets like F-16s, mainly to atagonise the Soviets in Afghanistan, but later deliveries were again embargoed and the USA only recently reimbursed their purchase fees. The USA-Pakistan relationship is one of the text-book examples of realpolitik.
