You have good imagination , USA is not so warm heart & stupid as you are.
If USA is so warm heart , it will not ban Huawei.
you are too naive if you think J-20 was designed by China by their own, do you think the hackers that stole F-35 data caught the Americans by surprise, you are too naive, China is the knife to attack Russia, Russia can not survive a two front war.
Do you think the Chinese will fill the gap of J-10 to J-20 in 10 years? too naive, the design of F-22 took 20 years after F-15 first flight, and 30 years after F-15 entered into service, do you think there are not classified documents that are kept secret and not taught in universities in the USA?
China thinks this is the century to reverse all the humiliations suffered in the XIX and XX centuries? haha, China is just a pawn to destroy Russia, but Russia will be not destroyed because Russia will become the light of both east and west.
The design of J-10 was made from Lavi technology and J-20 from Russian, Israeli and American technology from F-35 and MiG-1.44 and Elta radars, why do you think Clinton though China was to given preference status? do you think they do not know China demanded tech transfers? too naive.
