What this topic is asking
The United States entered World War II only after a direct attack, but it had been edging away from neutrality before then. The NGSSS benchmark SS.912.A.6 wants you to analyze the steps from neutrality to war (especially Lend-Lease and Pearl Harbor), the Allied and Axis powers, and the war's major turning points. This is a Reporting Category 2 topic the EOC tests with a quotation (FDR's "infamy" speech), a map, or a question about the cause of US entry.
The end of neutrality: Lend-Lease
Roosevelt argued that the United States must be the "arsenal of democracy," supplying the nations fighting Hitler. Lend-Lease was a major step away from the isolationism of the Neutrality Acts.
Pearl Harbor and the declaration of war
Pearl Harbor is the single most testable cause of US entry. Be careful not to confuse it with the World War I causes (the Lusitania, the Zimmermann Telegram).
The Allies and the Axis
The Allied leaders agreed on a "Europe First" strategy, defeating Hitler in Europe before turning their full strength against Japan.
The major turning points
Try this

Q2. State the event that brought the United States into World War II and when it happened. [2]
- Cue. The Japanese surprise attack on Pearl Harbor on December 7, 1941, after which the United States declared war.

Correct answer: the Japanese surprise attack on the US naval base at Pearl Harbor, Hawaii.
Markers reward identifying Pearl Harbor as the direct cause of US entry into World War II. Distractors such as the sinking of the Lusitania (a World War I event) or the invasion of Poland (which began the war in Europe but did not bring the United States in) place the cause in the wrong war.

A single-select item (Reporting Category 2, SS.912.A.6).
Correct answer: moving away from strict neutrality to support the Allies, even while not yet formally at war.
Markers reward recognizing Lend-Lease as a step away from isolationism toward aiding the Allies. Distractors saying the United States was strictly neutral, or already at war, miss the in-between role Lend-Lease represented.
