The Responsibility of States for International Propaganda

The tendency in recent world history toward the establishment of political parties based on class or racial ideologies in which no place of respect is given to established territorial boundaries has greatly intensified the problem of the responsibility of states in connection with international propaganda. Two main questions arise: (1) Are states themselves obliged under international law to refrain from spreading propaganda in a foreign country hostile to its government? and (2) Are they obliged to use due diligence to prevent private individuals and organizations from engaging in such activity? The purpose of this study is to seek the answer to these questions through an analysis of the sources of international law referred to in Article 38 of the Statute of the Permanent Court of International Justice: (a) international conventions, (b) diplomatic exchanges, giving evidence of international custom, (c) general principles embodied in municipal laws and judicial decisions, and (d) the attitude of writers on international law. Treatment of the subject will begin here with the period of the French Revolution and will be limited to peace-time political propaganda. The problem is, of course, much older and broader than these limits suggest, but it is believed that their extension would not contribute materially to the purpose at hand.
