In August 1952, as he was campaigning for the US Senate, John F. Kennedy addressed the Massachusetts Chapter of the American Federation of Labor. This manuscript is a draft of the speech Kennedy delivered before the influential labor union. Kennedy focused on the expansion of Communism and the priority of containment. Kennedy referred to the Communist threat as "an enemy, power[full], unrelenting and implacable who seeks to dominate the world by subversion and conspiracy."

He also pointed out that containment was necessary not only for United States military safety, but also because of the threat Communism posed in "political & economic" spheres.
