Those who argue for abandoning Ukraine on Taiwan’s behalf are, in effect, claiming to be more pro-Taiwan than the Taiwanese. That is arrogance, not prudence. Taiwan’s leaders understand how to deter China and protect their country’s security better than GOP politicians and think-tankers.Beijing’s extensive help for Vladimir Putin’s war effort shows that Xi believes a Ukrainian victory is bad for China. Russia and China are colluding in their support for autocratic aggression. The United States, Europe, Ukraine and Taiwan must all stand together to oppose them.
