War in Taiwan will dwarf Ukraine unless the US shows China its teeth | Simon Tisdall

Putin thought he could get away with his invasion. Xi Jinping must be deterred from making a similarly fatal miscalculation

It is generally acknowledged that a Chinese invasion of Taiwan, drawing in the US and possibly Japan, Australia and Britain, could dwarf the Ukraine crisis both in scale and danger. Top US generals and officials have repeatedly warned an attack is becoming more probable and more feasible. And yet it remains spectacularly unclear what the Biden administration would actually do in response.

The longstanding US policy of strategic ambiguity", designed to leave Beijing guessing about Washington's intentions, has helped keep a lid on cross-strait tensions. But the dynamic has changed radically with the rise of China's president, Xi Jinping, to a position of supreme power and the advent of his aggressive approach to Taiwan and international relations as a whole.
