Portugal during World War II
Upon the start of World War II in 1939, the Portuguese Government announced on 1 September that the 600-year-old Anglo-Portuguese Alliance remained intact, but that since the British did not seek Portuguese assistance, Portugal was free to remain neutral in the war and would do so. In an aide-mémoire of 5 September 1939, the British Government confirmed the understanding. As Hitler's occupation swept across Europe, neutral Portugal became one of the Continent's last escape routes. Portugal managed to remain neutral throughout the war despite extraordinary pressures from both sides, notably over the strategically located Azores islands and over the wolfram (tungsten) trade.
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.
