The first 'American Exceptionalists' belonged to a left-wing current led by Jay Lovestone. Briefly in control of, then dramatically expelled from, the US Communist Party, they maintained an independent existence on the US Left from 1929 to 1940. Lovestone himself collaborated with the CIA to help shape the Cold War foreign policy of the AFL-CIO. Yet earlier documents and articles from the Lovestone group provide rich information and remarkable insights on twentieth-century realities and radicalism.
