Definition
A policy of isolating one’s country from military alliances or other commitments with all other countries as a best resort to avoiding foreign entanglements. Historically a strong sentiment in the USA. President Woodrow Wilson won a second term in 1916 in promising (falsely) to keep America out of WWI, and the US was conspicuous in not joining the newly formed League of Nations. Prior to WWII aviator Charles Lindberg was prominent in the popular America First Committee which attempted to prevent the US being a participant in that war.
