The question has moved from speculative to urgent. With the Trump administration’s second term now producing a sustained record of signals, omissions, and transactional pivots, the Taiwan Strait is being scrutinized through the same lens that watched Ukraine’s western support erode — not in a single dramatic reversal, but in a slow dissolution of credibility.

The Ukraine comparison is structurally imperfect but politically instructive. Ukraine was abandoned not by a single decision but by a pattern: withheld aid, forced negotiations, bilateral summits that sidelined Kyiv. The mechanism was transactional pressure applied until a nominally sovereign partner had no viable alternative but to accept terms dictated by a larger power. Taiwan is watching that pattern and recognizing the template.
