It appears that how to counter a PLA invasion of Taiwan has become a national pastime for the Americans, at least among the community of armchair generals, retired generals as well as military think tanks. In general, views are overwhelmingly pessimistic that Taiwan can prevent the landing of PLA on Taiwan at all, even with the intended invention from the US. Nevertheless, these people aren't going to give up, or at least concede that the best option for Taiwan is to seek a political solution with PRC. That's not acceptable, ... for the Americans, simply because for them, it will be the end of American hegemony in Asia.
So what's the solution? A total war by Taiwan, as this National Interest article advises.
I'm almost moved to tears by the suggestion, which reminds me of maybe the best-known Churchill speech that he delivered to the House of Commons of the Parliament of the United Kingdom on 4 June 1940, during perhaps the darkest hours in WWII facing the British Isles.
In this case, the New World should probably be replaced by the US.
