What did the US sign in 1928 pledging it would never make war again?
The Harding and Coolidge administrations followed the policy of isolationism when it came to any meaningful cooperative causes with other nations. There were trade agreements and other commercial agreements that helped the US economy. But the US did not join the League of Nations and many Americans became convinced that it had been a mistake to intervene in World War I. In 1928, Secretary of State Frank B. Kellogg joined with the French Foreign Minister, Aristide Briand, to write a treaty outlawing war as an instrument of national party. The Kellogg-Briand Pact was signed by 62 nations, including the United States. Of course, the Pact was completely unenforceable. MrV
