Taiwan conducted a comprehensive ‘doomsday’ exercise that simulated a simultaneous Chinese military assault, cyber attacks, and an earthquake. Led by President Lai Ching‑te, the drill aimed to strengthen national defense and illustrated the worst‑case scenario: an earthquake that triggered a naval blockade, sabotage of critical infrastructure, and hijacking of television broadcasts by China, followed by civil crises and bank runs. The exercise focused on achieving full social resilience against escalating Chinese military pressure.
