In John F. Kennedy’s inaugural address, he proposed a major idea that people should unite and work together to promote liberty and rights. He stated that people had the power to modify the world: To destroy all forms of good or evil. Yet people should use it in the right places, which is to support allies and oppose enemies. And enemies can become friends through negotiations and cooperation. It is their duty to preserve the peace of the world.

Kennedy emphasized the right way to preserve peace through the use of antimetabole, a literary device that puts two opposite ideas together to create a contrasting effect.
