The F-16 fighter which America sold to the Pakistan Air Force, and recently tried to sell to India has been a relationship spoiler all round. Pakistan complains that American sanctions held back many F-16s that had already been paid for while India complains that Pakistan will use the F-16s against India, not terrorists, and now America is upset that India hasn't bought the F-16. The WikiLeaks cables talk about the F-16, what a great big deal it is in Pakistan, and how India isn't really worried about its fighting capabilities.
