When the U.S. Capitol was stormed in 2021, it was an attack on the very idea of America as a pluralist democracy. It was also a reminder that the worst threat to the United States today doesn't come from any foreign despot, but from domestic racism. In The White Storm, the journalist and author Martin Gelin looks back at two decades as a political correspondent and three centuries of American history to understand this moment of crisis. In the vein of Alexis de Tocqueville or Tony Judt, fellow Europeans who travelled America searching for answers to its political contradictions, this is a journey across time and space, from Thomas Jefferson's Monticello to the slave plantations of Louisiana, from mass prisons in rural Arizona to memorials for lynching victims in Alabama.

The book reveals how every step forward for black Americans is met with a fierce backlash from white Americans, taking two recurring forms: violent extremism and a flight from the commons. The white backlash always grows in proportion to the black advances. After Joe Biden was declared the winner of the 2020 presidential election, a black man at a polling station in Detroit said: "We used to pick cotton, now we pick presidents." It is precisely this black agency that white nationalists refuse to accept.

The White Storm reveals how racism has permeated almost every significant conflict in America's past. Now it threatens American democracy itself.
