EXPLANATIONS BELOW
Concept note-1: -Isolationists advocated non-involvement in European and Asian conflicts and non-entanglement in international politics. Although the United States took measures to avoid political and military conflicts across the oceans, it continued to expand economically and protect its interests in Latin America.
Concept note-2: -isolationism, national policy of avoiding political or economic entanglements with other countries.
Concept note-3: -Isolationism is a political philosophy advocating a national foreign policy that opposes involvement in the political affairs, and especially the wars, of other countries. Thus, isolationism fundamentally advocates neutrality and opposes entanglement in military alliances and mutual defense pacts.
Concept note-4: -Many nations in the past have been isolationist. These include China, Japan and Switzerland. The US attempted to do this in World War I and their failure brought more emphasis in the 1930s. The US was isolationist in the period leading up to World War II even while moving to become more involved once war broke out.
Concept note-5: -Another example of isolationism in the early 1900s was the cash-carry system the US had for the European countries. In short, this system involved European countries coming to America, buying weapons in cash, with no strings attached-this didn’t ally the US to any specific European country.
