I agree with Aero Wing 32, the first time I read the article, I thought it was another lobbyist as well. Real statistics will support a proper argument.
Why aren't there any IDF lobbyists? I'd be more willing to read an article on them instead of just US/TWN lobbyists all the time. Taiwan needs new second generation IDF planes, interesting thing...why does everyone start calling IDF C/D = IDF 2??? How about just producing new IDF C/D, like another 60-70 new fighters, and finish upgrading the rest of the fleet. Its better than F-5 and is easier to maintain, not to mention, you'll have more capable fighters.
The Americans probably would, after replacing them with F-35B's. Still a very competent WVR fighter as demonstrated by the Falklands War, and with the AV-8B Harrier II Plus, it is AIM-120 capable, with hardpoints that can carry 4 of them. The radar is also fairly capable, as it is the same one off the F/A-18 Hornet.Also... Harriers!?!?!?!!? What are they thinking!?!?! Harriers are a nightmare in terms of logistics, and have very limited capabilites as fighter aircraft, in fact, they are not fighter aircraft at all! They're carrier based attack aircraft, and who would sell them to Taiwan?

I think the major push for a VSTOL fighter is because Taiwan's airfields are so vulnerable to disabling attack. Even though steps have been taken to harden them, and preparations made to utilize highways as landing strips, if Taiwan had a VSTOL fighter that can essentially operate off any large solid flat surface, it would make it much more difficult for the Chinese to knock the ROCAF out of the fight by just targeting the runways; they will have to come to hunt down every single VSTOL fighter, and spend a lot of time and effort doing so, while increasing exposure. And if they don't neutralize this threat, they become the ROCAF's primary strike platform against the Chinese invasion fleet with bombs and missiles.
But wouldn't a more capable STOL fighter be a better choice compared to a subsonic VSTOL? The Harrier family may have been given the Argentinians a bloody nose but they were poorly trained and fighting with WVR weapons and radar systems, the AGP-65, while capable of firing the AIM-120 is only single target track capable and lack many features and capabilities of modern mechanical PD radars. Also we must consider than the F-35 is only coming around in 2015-2020 which means Taiwan would have to wait at the very least, 6 years for the first AV-8B Harrier II+ to be retired, the oldest of these airframes would over 20 years old by then. Taiwan would have to wait for the newer built AV-8B Harrier+s to be retired or have the older ones refurbished.
As an attack aircraft though, it would be extremely useful as you said, as a naval strike platform, a strong detterant but as of now, the ROCAF lacks a dedicated attack aircraft, it would have to readjust its military doctrines and procedures to integrate such units into the ROCAF. The lynchpin of all this though would be if the US would even be willing to sell its AV-8B Harrier II+ aircraft to Taiwan and if they would offer some sort of refurbishment plan like Lockheed Martin offered Argentina for the A-4AR Fightinghawk or an indigenous effort with American cooperation like Singapore's A-4SU Super Skyhawk upgrade.
