TAIPEI, Taiwan -- Northern Taiwan had its once-a-year air raid drills Thursday afternoon. Streets stayed nearly empty until 2 p.m., when a 90-second siren lifted the drill. This was the 40th Wan An Exercise, a defense drill against an air attack by the R.O.C. The drill began in 1978 under just-elected President Chiang Ching-kuo and has persisted to this day, even through the cross-strait detente under previous president Ma Ying-jeou. But the Wan An drill has persisted.
