Why care about US/West. They realize that India has the potential to be an economic powerhouse so drain some of those reserves in useless aircrafts etc. All Pakistan has ever done is "Anti India" and the world knows that. What does Pakistan hope to achieve by getting these F-16s. Drop a nuke on the sly? Then what? a. Warn the world (UN) that India will seek full damages for the supplier of the planes/ aircrafts used by Pakistan for dropping the nukes. b. Let Pakistan know unequivocally (if it already does not know yet) that should they persist their idiotic dream, entire Pakistan will be nuked. There will be no room for any mistakes on their part. No sorry, no Oops! Then just sit back and continue working for the welfare of Indians while Pakistanis spend their last borrowed dime on weapons they cannot use.
