António de Oliveira Salazar
Despite the authoritarian character of the regime, Portugal did not experience the same levels of international isolation as Spain did following World War II. Unlike Spain, Portugal under Salazar was accepted into the Marshall Plan (1947–1948) in return for the aid it gave to the Allies during the final stages of the war. Furthermore, also unlike Spain, it was one of the 12 founding members of the North Atlantic Treaty Organisation (NATO) in 1949, a reflection of Portugal's role as an ally against communism during the Cold War in spite of its status as the only non-democratic founder. In 1950, Portugal joined the European Payments Union and participated in the founding of the European Free Trade Association (EFTA) in 1960 and the Organisation for Economic Co-operation and Development in 1961. It joined the General Agreement on Tariffs and Trade in 1962, and finally, Portugal signed a free trade agreement with the European Economic Community in 1972, still under the auspices of the "Estado Novo".
World War II by country
Paraguay's authoritarian government under Higinio Morínigo was sympathetic to the Axis powers early in the war; the country's large German community in particular were supporters of Nazism, as well as most of the Paraguayan population. Serious thought was given to joining the war on Germany's side, but United States President Franklin D. Roosevelt avoided this by providing aid and military hardware in 1942. Paraguay declared war on Germany on February 2, 1945, by which time the war was almost over and many Paraguayans joined the Brazilian air force for fighting the Axis Powers.
