In regards to the American attitude that is reflected in They Met in Argentina, what president enacted that policy?
Good Neighbor policy The Good Neighbor policy was the foreign policy of the administration of United States President Franklin Roosevelt towards Latin America. Although the policy was implemented by the Roosevelt administration, President Woodrow Wilson had previously used the term—but subsequently went on to invade Mexico. Senator Henry Clay had coined the term "Good Neighbor" in the previous century.
American University speech The American University speech, titled "A Strategy of Peace", was a commencement address delivered by President John F. Kennedy at the American University in Washington, D.C., on Monday, June 10, 1963. Delivered at the height of his rhetorical powers and widely considered one of his most powerful speeches, Kennedy not only outlined a plan to curb nuclear arms, but also "laid out a hopeful, yet realistic route for world peace at a time when the U.S. and Soviet Union faced the potential for an escalating nuclear arms race." In the speech, Kennedy announced his agreement to negotiations "toward early agreement on a comprehensive test ban treaty" (which resulted in the Nuclear Test-Ban Treaty) and also announced, for the purpose of showing "good faith and solemn convictions", his decision to unilaterally suspend all US atmospheric testing of nuclear weapons as long as all other nations would do the same. Noteworthy are his comments that the United States was seeking a goal of "complete disarmament" of nuclear weapons and his vow that America "will never start a war". The speech was unusual in its peaceful outreach to the Soviet Union at the height of the Cold War, and is remembered as one of Kennedy’s finest and most important speeches.
