American foreign policy resonates with the same issues as the debate over U.S. entry into the League of Nations-collective security versus national sovereignty, idealism versus pragmatism, the responsibilities of powerful nations, the use of force to accomplish idealistic goals, the idea of America. Understanding the debate over the League and the consequences of its ultimate failure provides insight into international affairs in the years since the end of the Great War and beyond. In this lesson, students read the words and listen to the voices of some central participants in the debate over the League of Nations.

Using contemporary documents, students in this lesson explore the rise of animosity between the United States and Japan which began with Japan's "Twenty-One Demands" on China during World War I, and continued through the Manchurian Incident of 1931.

In December 1941, Japanese armed forces launched a massive offensive, attacking targets as far East as Pearl Harbor, Hawaii, and as far West as Burma. This lesson plan will focus on the overall strategies pursued by the Japanese and the Allies in the initial months of World War II in Asia and the Pacific.

The Japanese conquest of Manchuria in 1931 was only the first step in what became a much larger campaign to create a pro-Japanese "buffer state" in North China. This lesson will examine the overall principles which underlay both Japanese and American foreign policy in the mid- to late-1930s.

Although it was the Japanese who attacked Pearl Harbor in 1941, U.S. military planners decided that Germany, not Japan, was to be the primary target of operations. This lesson plan will focus on the overall strategies pursued by the Americans and their British allies in the initial months of World War II in Europe.

The outbreak of war in Europe in September 1939 posed a serious challenge to U.S. neutrality. On the one hand, Americans' sympathies lay overwhelmingly with Great Britain and its allies; on the other hand, public sentiment overwhelmingly favored staying out of the war. Through a study of contemporary documents, students learn about the difficult choices faced by the Roosevelt administration during the first fifteen months of World War II, culminating in the decision to provide direct military aid to Great Britain.

By the beginning of 1944, victory in Europe was all but assured. The task of diplomacy largely involved efforts to define the structure of the postwar world. Why and how did the United States attempt to preserve the Grand Alliance as American diplomats addressed European issues?

Although the campaign in the Mediterranean was successful in forcing Italy out of the war, Allied military planners by late 1943 had concluded that it would not be enough to defeat Nazi Germany. This lesson plan will focus on the overall strategy pursued by the Allies in the final months of World War II in Europe.

Faced with crippling economic sanctions imposed by the United States, the Japanese government decided in September 1941 to prepare for war to seize the raw materials that they were now unable to obtain from America. Students in this lesson will put themselves in the shoes of U.S. and Japanese diplomats in the final months of 1941.

For American diplomacy, the war against Japan was not just about the destruction of Japanese supremacy in the Pacific, China, and Southeast Asia. The ultimate issue was just what would replace Japan's imperial design of a "Greater East Asia Co-Prosperity Sphere." This lesson plan focuses on two major postwar problems"”the future of China and (using French Indochina as a test case) the future of Western imperialism in Southeast Asia.

The U.S. victory over the Japanese Navy at Midway succeeded in stopping the Axis advance in the Pacific, and by early 1943 the Marines had driven the Japanese from Guadalcanal. This lesson will guide students through the military campaigns of the Pacific theater, tracing the path of the Allied offensives.

This site provides a standards-based lesson on how the use of posters during WWII helped win over the hearts and minds of the American people.

The 1930s saw a steadily increasing campaign of Japanese aggression in China, beginning with the invasion of Manchuria in 1931 and culminating in the outbreak of full-scale war between the two powers in 1937. Each instance of aggression resulted in denunciations from the United States, but the administrations of the time understood that there was no will on the part of the American public to fight a war in East Asia.

In this curriculum unit, students reconsider the events leading to U.S. entry into World War I through the lens of archival documents.

This lesson plan explores the contributions of the Women Airforce Service Pilots (WASPs) during World War II, and their aviation legacy.
