As it often does, the US is demonstrating what the future could be for much of the world. Trump’s purges of immigrants, centralisation of power, suppression of dissent, rewarding of loyal oligarchs and contempt for truth and the law are not unique. Even governments which present themselves as alternatives to populism, such as Keir Starmer’s, increasingly share some of its features, such as a performative severity towards asylum seekers. Yet with over three years left of Trump’s frenetic presidency, and possibly more – were he to overcome the constitutional and electoral obstacles to a third term – life under him already provides the most unsettling picture of democracy under siege so far.
