The main worry of military planners here isn’t so much a full-scale amphibious invasion. Rather, they fear the mainland sowing chaos and disrupting the economy as a way of trying to bring Taiwan to heel.
Hence the concern about a cyberattack that would take out Taipei’s electric grid. Or sabotage of the underwater cables that bring data and internet to Taiwan. Or interference in the South China Sea with tankers carrying oil to Taiwan.
Wu added that China could also step up military pressure by increasing patrols in the area, or by holding military exercises. Even a partial blockade would have a substantial impact if it raised insurance costs and damaged confidence in the island’s future.
Government officials in Taiwan were cagey about how they would respond to provocations in cyber and other realms, but Wu said that military officials “are planning for defense and offense.” Another senior government official said that retaliation could include airstrikes on China’s Fujian Province.
