I am usually an utopian enthusiast of such wild ideas, but I see a problem here. Violence, in fact most violence in the world, is what Zizek would call Objective Violence. This is about the violence of the system. We are too worried about the Subjective violence, where someone is doing something to someone else, but this is different: This is sublime, everyday violence that robs people of their dignity and happiness. A prime example of objective violence will be the coalition government's policy to withdraw the benefits, without consideration and consultation, from lots of people. The implicit assumption, circulated in the media, was that most people on benefits are cheating the system, which is not true, but the government needed to demonize them to create the rationale for the withdrawal. Now, there are genuine people requiring benefits and they would possibly lose their homes because of the changes. This is objective violence manifested by the system.
This is the trouble with peace: While we talk about people shunning violence, we only talk about the visible, subjective violence we see. However, many of the incidents of subjective violence is manifested by the objective violence, the raw corruption of power, the subversion of informed opinion through media campaigns, etc. This is not a justification of subjective violence, but peace, shunning the physical, visible violence, will not have the desired magical effect till the time the systemic violence is so widespread. This is a harder challenge for those who are genuinely interested in changing the world.
