Ex-President Obama’s delivery of his speech is serious, brisk and formal, he nods his head for body language and this shows confidence in his words.
He uses a ton of Pathos, forcing the images and story of the tragic event of 9/11 into our heads by using Imagery by saying “Planes cutting through a cloudless September sky the twin towers collapsing to the ground, black smoke billowing up from the pentagon, the wreckage of flight 93 in Shanksville, Pennsylvania.” He uses the present tense to suggest these images are still present in our minds. He uses Pathos again to say that “Nearly 3000 citizens were taken from us leaving a gaping hole in our hearts”. After that, He moves to talk about the American nation as a whole. He uses logos to tell us that “Al-Qaeda” was the organization that led the attacks.
He uses alliteration “Disrupt, Dismantle and Defeat” the effect is to get things stuck in our heads.
He uses Diathesis to adjust his speech to the Muslims to say that the US is not at war with Islam, It gives the Muslims in the US a sense of security in their belief and their country.
