The early twenty-first century has been defined by a rise in Islamist radicalisation and a concurrent rise in far right extremism. In this book, Julia Ebner explores the interaction between the 'new' far right and Islamist extremists and considers the consequences for the global terror threat. Based on first-hand interviews, The Rage introduces readers to the world of reciprocal radicalisation and the hotbeds of extremism that have developed - with potentially disastrous consequences - in the UK, Europe and the US.
