This book is a collection of articles from members of AntiCapitalist Resistance, the Fourth International and other socialists arguing why the left needs to back working class and democratic struggles globally, and put the priorities of people first instead of reducing politics to geopolitical manoeuvres between governments. A healthy revolutionary ecosocialism fit for the 21st century will move on from the defeats of the left to plot a path for the overthrow of capitalism and imperialism through human liberation and solidarity.
