Abstract

In response to our critics, we explain why in spite of the ad bellum breach involved in the first use of force the war agreement is still binding; why the moral symmetry to which War by Agreement subscribes benefits all parties, weak and strong; why contractarianism leaves room the for moral option of not acting within one's rights and refusing to take part in a seemingly unjust war; why contractarianism is superior to rights-consequentialism as a theory of just war; and why contractarianism does not rule out reforms in international law and institutions.
