The correct answer is: The Kellogg-Briand Pact was meant to PREVENT FUTURE WARS.
The Kellogg-Briand Pact, also known as the Pact of Paris, was signed between the United States and 62 nations to prevent war as an instrument of national policy. The belief that diplomatic agreements could end war more efficiently as opposed to invasion inspired the treaty, and though it has been broken on several occasions it introduced the notion of 'crime against peace.'
