Concept note-1: -To help pay for the war, the government increased corporate and personal income taxes. The federal income tax entered the lives of many Americans. In 1939 fewer than 8 million people filed individual income tax returns. In 1945 nearly 50 million filed.
Concept note-2: -Isolationists believed that World War II was ultimately a dispute between foreign nations and that the United States had no good reason to get involved. The best policy, they claimed, was for the United States to build up its own defenses and avoid antagonizing either side.
Concept note-3: -At home, buying war bonds or savings stamps was probably the most common way to support the war. When people bought a bond or a savings stamp, they were lending money to the government. Their money would be paid back with interest after the war.
Concept note-4: -The United States later declared war on German ally Austria-Hungary on December 7, 1917. Germany’s resumption of submarine attacks on passenger and merchant ships in 1917 became the primary motivation behind Wilson’s decision to lead the United States into World War I.
