How Did The United States Reject Isolationism

In order to briefly talk about the American foreign policy, we must first understand the American outlook; what America thinks of itself. Americans have believed that the United states was different from nation states. Different in a sense that, they have always thought that they have (a) a special destiny and (b) A sense of mission. Now, since they have always thought of themselves as different from other nation states, that most important factors which influenced Americas self-image were: Isolationism, Moralism and Pragmatism.
Isolationism:
The causes of preference for isolation were geographical, emotional and mental in nature. Geographically, North America was separated from Europe by a vast ocean that took days, weeks and even months
