The American Committee on United Europe (ACUE), founded in 1948, was a publicly funded “private” American organization that sought to counter communism in Europe by promoting European federalism. Its first chairman was former head of the Office of Strategic Services (OSS) William Joseph Donovan, who had formally left the government after the war and was in private law practice.
The vice-chairman was Allen Welsh Dulles, who also had left the government and was in private practice. He later joined the Central Intelligence Agency (CIA) in 1951. who was recruited by the OSS when the US entered the war.
The structure of the organization was outlined in early summer of 1948 by Donovan and Dulles in response to assistance requests by Richard von Coudenhove-Kalergi, then Joseph Retinger and Winston Churchill, and resembled that of the Free Europe Committee.
An article in The Daily Telegraph in September 2000 noted, "The State Department also played a role. A memo from the European section, dated June 11, 1965, advises the vice-president of the European Economic Community, Robert Marjolin, to pursue monetary union by stealth. It recommends suppressing debate until the point at which 'adoption of such proposals would become virtually inescapable'."
