The West can’t afford to shun Russian oil
Donald Trump is a radical foreign-policy innovator. Over the past few decades, the US has tried a range of non-military means to nudge, squeeze and occasionally strangle its adversaries. These range from travel bans and banking restrictions, to export controls and trade limitations. But never has the US – or indeed anyone – tried to use import tariffs as a species of economic sanction. Trump has threatened Vladimir Putin with introducing “secondary sanctions” against countries that import Russian oil – a threat intended to strike at the heart of Russia’s war economy. And on August 4, Trump appeared, for the first time, to make good on that threat.
