Since World War I, US policy has been split between isolationism and internationalism. From debates over joining the League of Nations to intervention in Europe, Americans have found odd comfort in siding with one of these two camps.
The isolationists wanted to avoid being mired in foreign intrigues, wars, and crises. The internationalists argued that without involvement, the world would evolve in ways that lacked US influence and thus threatened its national security. On December 7, 1941, the internationalists won the debate.
The problem was that the friction was not between true isolationists and internationalists. The fact was, there were no genuine isolationists. The debate was actually between two internationalist strategies. The clash between these two camps has been ongoing since the founding of the United States. It is an issue that is simmering towards a boil again today.
During the 1930s, this debate centered on the best way to handle Europe. One side argued that the US had to play a role in shaping Europe.
The counterargument—dubbed isolationism—was that trying to shape Europe was a trap. The Europeans had been engaged in an endless struggle. The US had fought in World War I without ending the continent’s conflicts, and it should not be drawn into another war.
It should be noted that the so-called isolationists did not, in general, object to US involvement in China. The US sent gunboats to patrol its rivers, gave military aid to China, and permitted American airmen to volunteer to assist the Chinese.
The story was different for Europe. There was no desire for US engagement. This reflected the reality that the US Army was extremely small, but was the largest force it could field. If deployed, it would be readily overwhelmed by German forces.
So, the internationalists wanted to involve the US in Europe and, to a lesser extent, in China. The isolationists pressed to avoid involvement in Europe and for limited action against Japan. This was not, however, a struggle between isolationists and internationalists. This was a contest between competing internationalist strategies that both supported some degree of foreign engagement.
A Revolutionary Idea -
Those that support what they believe to be isolationism frequently cite Thomas Jefferson’s warning against involvement in entangling alliances. Yet, the American Revolution was won only because the colonies used extensive diplomacy and alliance building.
Benjamin Franklin was sent to Paris to recruit the French government to the side of the US. Franklin used the conflict between Britain and France to try to position the US as a French ally. The French, at first, provided some covert supplies to the US during the revolution. France would later make a large-scale commitment to the US because it wanted the British defeated in North America.
