What arguments were made in favor of isolationism?
The isolationists held the perspective that America was different from the European societies. America could advance the cause of democracy and freedom through other ways than war, or they believed that issues would be resolved in other ways as possible.
How and why did America’s isolationist stance erode entering into the 1940s?
World War II, Americans, joined the war after the attack in Pearl Harbor and increased the military preparedness and its related unemployment in the US led to America’s isolationist stance to erode during the 1940s. Americans were ready to defend the country from the intruders, Japanese force, not for popularity or recognition. There was a severe slowdown in terms of economy, and the unemployment rose eventually wherein the Americans feared that the economic boost was over, and people would suffer.
How did American foreign policy goals shape the American approach to the war?
When it comes to policy, America has divided personality, being pragmatic and realist. If one method does not work accordingly, then the other method does to solve the issue at hand. Both approaches taught Americans to respond to the situations, and rational decision-making is in the process to resolve the issue. For Americans, the success is possible if there is at one point as balance on the resources and its capabilities with the liabilities and objectives.
