According to the following article -
- US Approves To Sustain Pakistan’s F-16 Fighter Jet Fleet; To Reverse Trump-Era Suspension Of Security Assistance
The US Defense Security Cooperation Agency (DSCA) notified Congress on September 7 of the State Department’s decision to approve the possible Foreign Military Sale to Pakistan of F-16 Case for Sustainment and related equipment for an estimated cost of US $450 million.
The proposed sale does not include any new capabilities, weapons, or munitions and will not alter the military balance in the region.
My question is, how does the USA determine the military balance of South Asia? Is it only based on US-made platforms?
