I'm going to reiterate a point I don't think I emphasized enough earlier. Pacifism will not save the world. Pacifism will not change the world, either. Brutal dictatorships are not going to change their ways just because we talk to them. There must be a credible threat of force if things are to be changed. And in many cases, the threat will have to be carried out. Bluffing will not work, either. If we're going to change the world for the better, we're going to have to do more than sacrifice ourselves: we're going to have to hurt other people, too.
