Book excerpt: Militarism is the elephant in the room of global warming. Of all government sectors, 'Defence' has the highest carbon footprint and expenditure, yet has largely been exempt from international scrutiny and regulation. Marty Branagan uses Australian and international case studies to show that nonviolence is a viable alternative to militarism for national defence and regime change. 'Active resistance', initiated in Australian environmental blockades and now adopted globally, makes the song 'We Shall Not Be Moved' much more realistic, as activists erect tripod villages, bury, chain and cement themselves into the ground, and 'lock-on' to machinery and gates. Active resistance, 'artistic activism', and use of new information and communication technologies in movements such as the Arab Spring and 'Occupy' demonstrate that nonviolence is an effective, evolving praxis.
