In what two ways did the United States try to promote peace during the 1920's?

During the 1920s, the United States promoted peace primarily through diplomatic initiatives and arms control agreements. The most notable effort was the Washington Naval Conference of 1921-1922, where major naval powers agreed to limit naval armaments and prevent an arms race. Additionally, the U.S. played a key role in establishing the Kellogg-Briand Pact of 1928, which sought to outlaw war as a means of resolving disputes, reflecting a commitment to peaceful conflict resolution.
