What was a key outcome of the Kellogg-Briand Pact of 1928?

The Kellogg-Briand Pact of 1928 is a significant diplomatic agreement that represented a hopeful step towards international peace in the aftermath of World War I. The key outcome of this pact was the formal renunciation of war as a tool for resolving international disputes by 65 nations. This resolution was particularly notable as it reflected a collective aspiration among many countries to promote peace and discourage aggressive military actions.

The pact, initiated by the efforts of French Foreign Minister Aristide Briand and U.S. Secretary of State Frank B. Kellogg, aimed to ensure that war would be outlawed as a means of policy, positing that nations should instead resolve their disagreements through peaceful and diplomatic means. Although the pact had no enforcement mechanism, and countries continued to engage in military conflicts afterward, it symbolized an important moment in the history of international relations by fostering the idea that treaties could serve to uphold peace.
