American chaos is already oozing over the border: the trickle of refugees crossing after Trump’s election has swollen to a flood; a trade war is underway, with a US trade representative describing Canada as “a national security threat”; and the commander-in-chief of the most powerful military the world has ever known openly praises authoritarians as he attempts to dismantle the international postwar order. The US has withdrawn from the UN Human Rights Council, pulled out of the Paris climate agreement, abandoned the 2015 Iran nuclear deal, and scorned the bedrock NATO doctrine of mutual defence. Meanwhile, the imperium itself continues to unravel: the administration is launching a “denaturalization task force” to potentially strip scores of immigrants of their US citizenship, and voter purges are on the rise.
