Taiwan and a blockade

People still talk about Taiwan as if the opening scene is paratroopers over Taipei. That scene is possible. It is also the most expensive, most visible, most likely-to-unify-Asia-against-Beijing version of the crisis. A blockade, or a quarantine with a legal story attached, is cheaper, denser, and harder for Washington to answer with a slogan.

Taiwan is an island that imports energy and exports chips. Those two sentences are the whole vulnerability. You do not have to take the presidential office to make the lights flicker. You have to make insurers, ship captains, and LNG cargoes hesitate. Markets hesitate faster than marines.

The United States has spent years talking about "defending Taiwan" as if defense were a switch. Defense against an amphibious landing is one toolkit: mines, missiles, submarines, a messy fight in the strait. Defense against a blockade is another: stockpiles on the island, gray-hull escorts, a willingness to dare a shooting incident over a civilian tanker, and allies who will still dock. Those are not the same appropriations request. Congress keeps funding the movie.

China's tools fit the slower version. Coast guard, maritime militia, customs inspections, "illegal" sand dredging, cable cutting, cyber against ports. None of that looks like D-Day. All of it looks like a shipping delay that becomes a political crisis in Taipei before it becomes a CNN map with arrows.

Deterrence still matters. A PLA that thinks it can strangle the island in a month without a U.S. response will try, if the mainland politics demand a win. A PLA that thinks a quarantine becomes a U.S.-Japan problem by week two may wait. Waiting is not peace. It is a clock you can use to harden the island: energy reserves, redundant cables, civil defense that is not a pamphlet.

Chip leverage cuts both ways. The world needs TSMC. China needs TSMC too, which is a reason not to bomb the fabs and a reason the fabs are a hostage. "We will move the plants to Arizona" is a decade, not a weekend. Policy that treats Arizona as a substitute for the strait in 2026 is lying with a groundbreaking photo.

Allies are the tell. Japan cannot pretend a blockade is a local Chinese matter if the sea lanes and the U.S. bases on Okinawa are in the mix. Australia, the Philippines, Korea each have a different pain threshold. A U.S. policy that does not name those differences will discover them in the first week, on television.

I do not want a war over Taiwan. I also do not want a quiet surrender dressed up as "status quo." The status quo is already a daily squeeze. The analytical job is to price the squeeze, not to wait for the landing craft so we can feel like we finally have a simple story.

If Washington is serious, the boring list is the real list: munitions stocks, fuel on Taiwan, undersea cable repair, legal authority to escort, and a public line that a quarantine is an act of war even if nobody has stormed a beach. If that list is too dull for a rally, the rally is not the policy.
