Here are some easy predictions: In the years ahead, we are promised austerity, poverty, violence, and ecological catastrophe. If societies want to deal with any of these problems, they will also have to deal with the problem of war, because through all this, we will also have war. As a result, people will need to develop antiwar movements. The arguments that those movements will rely on will be the same ones that are mocked today, the very same ones that used to be more widely accepted, but have somehow been forgotten.
