You mean Keys and Blain, compared to them I'm just an amature.Neo i know u r a expert on aviation matters but u will agree with me that stranger things have happened.
Stranger things have happened and once Pakistan was indeed the major recepient of US' latest technology. PAF was first to get Lockheed F-104 Starfighter in the sixties making her the first airforce in Asia to have a mach 2+ interceptor.
US will need to market the F-22/F-35 in the international market for its aviation business to survive and really why not pakistan? (in 2020)
Pakistan will be a major weapons producer and buyer by 2020, we'll see more JV's with Chinese and European consortia and have a Chinese (probably co-financed) Stealth fighter in the picture making US' FMS to less attractive.
US' balance is already shifting towards India, the bigger fish which has more $$$ to spend than Pakistan.
Imho US will eye Indian Stealth requirement to counter PAK-FA which will suffer signifacant delays and probably financial problems due rising development and production cost. The project is already a decenium old and India joined the JV only last year. My source told me that there are already financial issues since both India and Russia are growing by 7.5-8% p.a. and the propesed proposed production line in India will become more expensive than Russia by 2015!!
So India will remain is potential market for US' stealth, F-35 rather than F-22 which isn't for sale anytime soon.
F-35 will only be offered to us when J-XX is available, not earlier.
