The big question for the US president-elect, Joe Biden, who has taken “build back better” as his motto, is whether this will mean genuine renovation or mere restoration. Americans desperately need a pivot after the madness of Donald Trump. And when Biden takes the reins of power from his predecessor, there is no doubt that a big reset will come. But the risk of complacent restoration is nowhere greater than in US foreign policy – especially since it is a domain in which the office of president has so much authority, even in the midst of legislative gridlock.
