Which rhetorical device is most prominent in this excerpt from john f. kennedy’s inaugural address?

so let us begin anew—remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. let us never negotiate out of fear. but let us never fear to negotiate.

let both sides explore what problems unite us instead of belaboring those problems which divide us.

let both sides, for the first time, formulate serious and precise proposals for the inspection and control of arms—and bring the absolute power to destroy other nations under the absolute control of all nations.

let both sides seek to invoke the wonders of science instead of its terrors. together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.

let both sides unite to heed in all corners of the earth the command of isaiah—to "undo the heavy burdens . . and to let the oppressed go free.”
