The Atlantic Charter, signed on June 22, 1941 by President Roosevelt and British Prime Minister Winston Churchill, reflected growing American support for a policy of  international involvement .

Explanation:

The Atlantic Charter was a joint declaration signed on August 14, 1941, aboard the USS Augusta, "while sailing somewhere in the Atlantic", by President Franklin Delano Roosevelt on behalf of the United States and Winston Churchill on behalf of Great Britain.  

The Atlantic Charter was reminiscent of the idealism of Wilson's Fourteen Points. It was later incorporated into the Declaration of the United Nations approved on January 1, 1942.

This document was not a treaty between the two powers. Nor was it a definitive and official definition of the ends of peace. As the same document expressed, it was an affirmation of "certain common principles in the national politics of our respective countries, in which the hopes for a better future for humanity lie."
