The point I would take, as a US ally, is that regardless of how trustworthy and honorable a particular US administration is, and the American people are, and the American military is, you never know when a Machiavellian globalist will take over, and pull out the rug from under you, without mercy. I don’t think the Taiwanese are going to get any comfort from the idea that their situation is completely different from Afghanistan’s. I expect they’re frantically reviewing a Plan B.
I would be willing to bet that plan B is spelled, “N.U.C.L.E.A.R.”
