With the outlawing of war in the 20th century, war has not disappeared. Rather, the need arose to justify a new form of use of force in order to guarantee compliance with international norms and enforcement of the ban on war. So-called “sanction wars” were already controversially discussed in the 1930s and still represent a political, legal and ethical challenge today. The paper (1) explains what sanctions are and under what conditions one can speak of sanction wars, (2) explains the varying political expectations that were and are placed on sanction wars, and (3) what empirical evidence exists about the effect of unilateral military sanctions on certain norms and the normative order of the international system as a whole.
