What North Korea and Iran are to the United states,Pakistan is to India.So its but obvious India wouldn't like the pakis getting any military hardware from the USA.
The F-16's are nuke delivery systems which is the major concern .It is a fact that the pakis r gonna use them against India whreas India needs to buy stuff as a deterrent to China.
The IAF need not worry abt the JF-17's .They have chinese avionics!!
