When the US Government thinks about outer space, it thinks not about exploration or science, but about weapons. Believing that wars fought from space are inevitable, President George W. Bush has called for the weaponisation of outer space - a proposal which could provoke a hugely expensive and potentially catastrophically dangerous new arms race. Contrary to Donald Rumsfeld's claim that the US faces a space Pearl Harbor', the authors of this book show how the US itself is the principal obstruction to an international treaty banning weapons from space.'
