What is the difference between isolationism and interventionism in United States foreign policy?

Isolationism means the U. S. withdrawing from foreign interaction and keeping to their domestic affairs, while interventionism is the opposite, the U. S. ignores their domestic affairs and chooses instead to interact with foreign affairs

Isolationists claimed that U. S. aid for Great Britain would increase the likelihood of actual American involvement in World War II. Internationalists claimed that it would make U. S. intervention less likely. Based on the actual events of 1941, which do you think was closer to the truth, and why?"
