Elizabeth Coatsworth uses short, quick words in the first stanza of "Swift Things Are Beautiful" because they d. contribute to the ongoing metaphor in Coatsworth's work. In my opinion it's the most correct option.
"They...<span>think that there is nothing more inglorious than that glory that is gained by war"
This quotation sums up the main idea because it not only reinforces to the reader that they are against war, but it gives some insight into why they are against war. The people think that there is no glory to be gained in war, so they choose to just prepare a defensive army, never an offensive one. </span>
