Throughout his speech, Kennedy persuades people to come together and stand up to take action. One of the president's literary devices was to use extreme adjectives to emphasize his points. For example, Kennedy states: “In the long history of the world, only a few generations have been entrusted with the role of defending freedom in the hour of greatest danger. » In doing so, he emphasizes his arguments and urges the people to agree with him, building consensus rather than openly expressing his desire that the people follow his course of action. Additionally, using exhortative phrases provides a more inviting tone to the audience. For example, in paragraphs 27 and 14 he says “let us” instead of “we will”. This helps people feel like they are helping to change the issues, which ultimately serves the purpose of the essay by making the audience feel more unified with their own content..
