If the italicized word in the sentence is <em>who, </em>then the correct answer is that it is an <em />interrogative pronoun, which means that is asks a certain question.
Answer:
building up its supply of military weapons
Explanation:
In order to preserve and safeguard the four freedoms in a democratic country like the United States, it has to build adequate military weapons to counter the aggressive and Fascist regimes. A strong military might will ensure the security of the US in case it has to deal with aggressors and dictators. President Franklin D Roosevelt spoke four freedoms amidst World War II when Germany was aggressively pursuing war and to impose dictatorial regime under Hitler.
I believe that the best answer for this question is the Nez Perce War. The War broke out when the U.S. Army pursued 750 Nez Perce, led by Chief Joseph, who were fleeing away from Idaho and towards freedom. The Nez Perce outfought their opponents, but eventually, Joseph formally surrendered. After the war ended, the Nez Perce were shuttled to prisoner of war camps for eight months. Chief Joseph went to see the President to plead his case. Hope this helps.
