The document outlines the idea of collective security, which was set forth in the Covenant of the League of Nations, as all countries defending another facing international aggression. The League was to take three steps to deal with aggression - condemn and demand the aggressor stop, impose economic sanctions, and use military force. For collective security to work, the League required goodwill, political backing, and material support from its members, and relied on the United States as the only powerful enough country to guarantee international support.
