Taipei ran police blockades on the bridges into its own capital this week, part of a war drill that also throttled internet speeds and rehearsed a tunnel blockade meant to stop People's Liberation Army forces from moving through the city. Taiwan's coast guard, the smaller service historically built for fisheries patrol and smuggling interdiction, is being armed for direct confrontation with Chinese vessels. Neither move treats invasion as a distant contingency. Both are logistics for a specific afternoon: the one when Beijing's coast guard and PLA assets are already inside Taiwan's contiguous waters and the government has hours, not weeks, to move personnel and slow an advance through Taipei's own streets. Washington's response, delivered through the State Department, was a request that Beijing halt pressure on Taiwan. The request and the drill are not answering the same question.

Taipei's planners are building for the days after a blockade begins, which means they have already concluded that deterrence, on its own, will not hold that day. A bridge blockade drill only pays off if the bridges are contested, which means the exercise assumes PLA forces reach the capital's perimeter. Washington's statement, filed the same week, asks Beijing to stop something without naming the something, which leaves Taipei to plan for the case where the ask goes unheeded. The next signal to watch is whether Taipei's Ministry of National Defense schedules a second capital-level drill before year end. One is a rehearsal. Two, within months, is a standing assumption.
