Partnership means TOT. Is the U.S. ready for TOT for critical systems? How can the U.S. assume India to counterbalance China in IOR without sharing technology? On one side Trump is coming up with strong statements against India and on other side talking about partnership?
They should have consistency in what they intend, speak and do.
That's why one should never trust the damned 'red necks' in the first place, all they do is show double standards. But unfortunately it's our necessity right now. This wouldn't have been a problem if our Tri-service command put some faith in indigenous manufacturing, "abhi tak to sabh foreign maal tha". If the progress we are making, which is still slow IMHO, but slowly but steadily we are achieving indigenous manufacturing skills.
I still doubt there tech though, because they still eavesdrop on military services using there assets they've sold to many, for example ... an ATC at Edwards air force base already knows that an F16 is active and about to make a sortie. This kind of telemetry is more hardened across there F35 variants. With real time tracking of each asset as soon as it lifts off.
I hope we didn't made a grave mistake by making deal with the devil, in short ... LAMOA
