Donald Trump’s Oval Office tirade on Friday laid bare his instinct to harangue and bully those – even supposed allies such as Ukraine, fighting for its survival – who dare to disagree. Countries pushing global tax reform at the UN will be watching as US demands for subjugation play out in plain sight. His day-one threat to punish nations taxing US firms is an all-out attack on global fiscal cooperation. If multilateralism in taxation was already on shaky ground, Mr Trump’s return could bury it for good.
