This chapter discusses international diplomacy and America's changing role in the world from 1921-1941. It covers topics like early 20th century agreements like the Kellogg-Briand Pact, the rise of isolationism in the 1930s as shown by the Neutrality Acts, President Roosevelt's increasing efforts to aid allies like the Lend-Lease program, and concludes with Japan's attack on Pearl Harbor that led to America's entry into World War II.

“We should seek by all means in our power to avoid war, by analysing possible
causes, by trying to remove them, by discussion in a spirit of collaboration and
good will. I cannot believe that such a programme would be rejected by the
people of this country, even if it does mean the establishment of personal
contact with the dictators.”
- Neville Chamberlain
