Security has become the governing ideology of our contemporary age. In its name bombs are dropped, uprisings suppressed, walls erected, weapons sold, and countless numbers spied upon, imprisoned, tortured, and killed; and yet, despite the monumental economic and political resources expended in pursuit of security, life for most people feels less, not more, secure. Threats – whether economic, physical, environmental, imperial – abound, and a future of perpetual financial, military, and ecological crises beckons. Meanwhile, in a series of cruel ironies which those familiar with radical politics know only too well, the supposed agents of security are frequently those propelling and profiting from these abundant insecurities.
