What extended responsibility did franklin d. roosevelt feel was a duty of the united states?

IT was the worst of times when Franklin Delano Roosevelt assumed the presidency in March 1933. Following the ruinous stock market crash of late 1929, the bottom seemed to drop out of the American economy. By 1933, securities listed on the New York Stock Exchange had lost more than three-quarters of their 1929 value. Industrial production had fallen to half its 1929 level. Agricultural income had plummeted even more sharply. Piles of unmarketable wheat flanked railroad tracks across the plains states. Desperate Iowa farmers blockaded the approaches to Sioux City in the summer of 1932, assaulting vehicles that tried to breach the makeshift barricades of logs and spiked telephone poles.
Hope this helps
