According to Elbridge Colby, a former US defense official, China could attack Taiwan with little or no warning as the Xi Jinping-led government has given up on ‘peaceful unification.’ Colby, who served as the deputy assistant secretary of defense from 2017 to 2018, advises the US to shift its support from Ukraine to Taiwan and strengthen its military to deter Chinese aggression. He suggests that such an attack could involve US troops and allies in the Asia Pacific region. Colby also believes that Europe can handle Russia on its own while Asia requires more support in the face of Chinese threats.
