The Kellogg-Briand Pact was useless because its failure to define "self-defense" led to many loopholes, and the pact, which was designed to prevent further world wars, did not prevent World War II. The Kellogg-Briand Pact was signed on August 27, 1928 by 15 nations, with 47 more following suit.
According to the U.S. Department of State, the Senate ratified the Kellogg-Briand Pact with an 85-1 vote. However, they made a stipulation that there would be no limit to self-defense rights nor any action requirement on the part of the United States if signatories broke the agreement. The 1929 Nobel Peace prize was given to Frank Kellogg, and the pact, though ineffective, stands as an idealistic symbol for the idea of peace between both world wars.
