where is that like button?
It doesn't seem to matter that the AV8 may not be effective against PRC CAP, they will have their hands full dodging MANPADS and similar. What is valuable is the opportunity to go and do some CAS from FOBs that are essentially unprepared. The distribution of the air assets allows them to last long enough to be an impediment to the beach heads. There is possibly more value in buying gallons of DJI drones, or amping up drone production in Taiwan, Alibaba's orderbooks are probably going to be full or limited to rogue regions, and more MANPADS than PRC has air assets.
Much as I enjoy nostalgia, if anyone thinks 50, or even 100 Harriers will make a difference to Taiwan in the event of a conflict with China... I suggest you haven't been paying attention.
