The distinction Taiwan's Ministry of National Defense has drawn for two years, between a blockade and an invasion, collapsed this week. Chinese coast guard cutters and People's Liberation Army aircraft tightened patrol patterns around Taiwan's air and sea approaches, the kind of layered presence that doesn't announce itself as an exercise because it isn't one. The Institute for the Study of War's continuing satellite tracking of PLA buildup along the strait places amphibious and landing-force assets ahead of the general invasion timeline Admiral Samuel Paparo, head of US Indo-Pacific Command since 2024, has cited before Congress: full invasion capability by 2030. Blockade capability, the lower bar, reads as achieved now, not projected.

Taiwan's own military has stopped pretending otherwise. The Han Kuang exercise this cycle dropped the scripted choreography of prior years for live-fire stress testing under compressed timelines, an implicit admission from Taipei's General Staff Headquarters that the drills exist to answer the question a blockade actually poses: how long the island holds without resupply. A blockade doesn't require Beijing to fire first. It requires Beijing to hold the strait long enough that firing becomes someone else's problem. What changes if the 2030 window is real: the NT$1.12 trillion conventional buildup Taipei funded in August is a bet it has four years, not more, to make the strait cost more than Beijing is willing to pay.
