headlines: As China Rattles Sabers, Taiwan Asks: Are We Ready for War?
articles: Underlying Taiwan’s defense dilemma is a question left unanswerable by design: Will the United States send military forces to Taiwan’s aid? In May, President Biden suggested he would, but the United States offers no explicit security guarantees, a strategy it hopes will avoid either provoking Beijing or emboldening Taiwan to declare formal independence.
  
  Mr. Xi has said he seeks a peaceful unification with Taiwan, and he may be deterred by the huge economic and diplomatic blowback China would suffer for an invasion. But China has also been pointed in its warnings. Its defense minister, Gen. Wei Fenghe, said over the weekend that Beijing would “fight to the very end” for Taiwan. It is sending fighter jets toward the island almost daily — including 30 aircraft in one day last month alone.
  
  The concern is that such maneuvers could, intentionally or otherwise, be a prelude to conflict.
  
  “We cannot wait; we are competing with time,” said Michael Tsai, a former defense minister of Taiwan. “Russia’s invasion of Ukraine happened in an instant — who knows when the P.L.A. might choose to invade Taiwan.”
  
  The ‘Porcupine Strategy’
  
  Several military drills conducted in January were intended as a show of force to China — to demonstrate how Taiwan planned to stop invaders from intruding on its airspace, landing on its beaches and, in the worst case, taking over its cities.
  
  At an air base in central Taiwan, a siren wailed, and within minutes pilots were taking off in F-16 fighter jets to ward off intruders. Off the northern coast, the navy debuted new mine-laying craft as two small warships fired live ammunition. In a southern city, smoke filled the air as soldiers practicing urban combat shuffled past fake storefronts of bubble tea shops and cafes, exchanging gunfire with combatants.
