Most F-16 customers don't have an interest in developing their own AAMs.I'm not sure they really need more than that.
Unless they believe deep-strike is the best form of defense, they just need something with newer AESA radar, IRST, and ability to launch home made AAMs.
US has never allowed ROCAF to integrate TC series AAMs to F-16 which means there are a maximum of 2 AMRAAMs per all flyable F-16s. That is a joke. Why only Israel is allowed this special privilege?
Sometimes I think US is simply extorting TW.
The Turks have integrated the Bozdogan onto the F-16 as well.
