Several days ago, some 27 US senators expressed their concern against the Turkish drone program.
Nowadays, a lot of nations have manufactured and sold drones including China.
So, why is the USA particularly concerned about Turkish drones?
Is the USA concerned because Turkey is an official NATO ally but selling drones against NATO interest, or, is it because Turkey is slowly possessing the drone market and hurting the US sales?
Would it be okay for the USA if Turkey stops manufacturing and selling drones but China, Russia continue to do the same? Why is that?
Is there any similar example of the USA taking measures against a country for a similar reason?
