Just Peacemaking
I for one am an advocate of "Just War Theory". However, I heard an interesting speaker at a conference at DenSem last year that I would encourage you to research. His name is Dr. Glen Stassen and he's a prof at Fuller. He is an advocate of what he calls "Just Peacemaking". Check out his website for more info http://www.fullerseminary.net/sot/faculty/stassen/cp_content/homepage/homepage.htm
