How does the figurative language in line 1-4 develop the poems theme?

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

as we know, the english language is spoken all over the world by native and non-native speakers and has become the most certain tool when it comes to communicating. businesses, schools, even romantic relationships depend on it to keep thriving. in addition, it is the language of the internet not only because most of the content available is in english, but also because people prefer to use it when talking to others, since it's the language everyone supposedly learns.

yet, there have been some current claims that chinese will soon take over as the most important language in the world. china's magnitude has never been more evident and doing business with the chinese is a gold mine for any country. we now see language schools offering chinese courses as commonly as english.

however - even though we cannot deny china's importance and the advantage it is when someone takes the time to learn the language their business contact speaks-, people in general seem to be ignoring the aspects that seem to keep english as the chosen one of languages. one of them has been mentioned above: it is the language of the internet. also, chinese people are still learning english, since it opens doors in communicating with practically everyone else, from every single country.
