During the four years of Donald Trump's presidency questions of race discrimination and
ethnonationalism have been gaining importance in American culture and politics once again.
Racism and antisemitism have been tolerated and at times even encouraged by the current
administration's policies and actions ranging from the so called Muslim ban and the constant
demands for building a wall on the Mexican-American border to openly calling the neo-Nazi
marchers in Charlottesville very fine people and to the events following the killing of George
Floyd. All this alongside the Covid-19 pandemic has impacted the social and political climate
in the USA even though the roots for current problems and polarizations reach deep into the
American past. This volume examines recent developments in comparative perspective analyzes
their histories and discusses their possible impact on the future.
