Before and after World War II, trade policy was largely dealt with, and shaped by, the communities of government economists and diplomats. Lawyers were hardly involved or in the lead. John Maynard Keynes and Harry Dexter White coined the Bretton Woods institutions. Clair Wilcox was instrumental in creating the General Agreement on Tariffs and Trade, and Joseph Viner influential in the early years of the GATT. All were economists. Harry L. Hopkins, the father of New Deal and senior adviser to President Roosevelt, entered social work and government after college. In 1944, he coined the adage, expressing the philosophy of international cooperation, which would influence subsequent generations and legal developments so strongly: ‘Trade conflict breeds non-cooperation, suspicion, bitterness. Nations which are economic enemies are not likely to remain political friends for long.’
