What should we be doing?

When dealing with Genocide why are we so reluctant to take action even when alternative solutions appear to be failing miserably. An article on CNN.com from Sunday showed us that what the world needs is not peace talks but action. According to the AU envoy, "the process leading to negotiations has begun," and yet how is this possibly going to effect change if the first scheduled "peace talk" does not enjoy the presence of the rebel leaders? UN mediator Jan Eliasson claims that "the real substantial negotiations will start when the parties are prepared," and yet how can we guarantee that rebel groups will ever be "prepared," more importantly what are we doing in the meantime so that when they fail to show up for another "peace talk" action is taken?
