This time it's about American isolationism. The relationship between the United States and Europe is greatly related to the overlap between the founding period and the confusion caused by the French Revolution in Europe. France repeats twice the rotation of governmental forms from the monarchy through the republic to the imperialism, and played the role of the ignition point of the liberal movements in Europe. In response to this confusion, Jefferson, the third president, Monroe, the fifth president, inherited an isolationist policy that distanced itself from Europe. However, for the people at that time, where most of them were immigrants from Europe, Europe was also a nostalgic place where their ancestors lived. When Irish Kennedy, Reagan, and the current president Biden visited Ireland, it also meant a homecoming. In other words, while it was also a place that American people wanted to go to Europe fondly, it was also a confusing and problematic place where their ancestors were forced to emigrate. In short, in that era, it has been decided by which emotion was dominant whether it was isolationism or internationalism. In the United States after World War I, isolationism prevailed because the whole society became conservative due to the economic development of its own country and the advent of mass consumption society. The socialization in one country of the Soviet Union was also added, creating a favorable situation for Germany, which had a larger population of 20 million people than Britain and France respectively.
