Neutral powers during World war II - wikipedia Neutral powers during World war II Jump to : navigation , search Allied Powers Allied Powers after the attack on Pearl Harbor Axis Powers The neutral powers were countries that remained neutral during World War II . Some of these countries had large colonies abroad or had great economic power . Spain had just been through its civil war , which ended on 1 April 1939 ( five months prior to the Invasion of Poland ) -- a war that involved several countries that subsequently participated in World War II . During World War II , the neutral powers took no official side , hoping to avoid attack . However , Portugal , Sweden , Colombia , and Switzerland all helped the Allied Powers by supplying `` voluntary '' brigades to the United Kingdom , while Spain avoided the Allies in favor of the Axis . Ireland generally favoured the Allied side , as with the United States . The United States remained neutral until December 8 , 1941 , a day following the sneak attack by Japan on Pearl Harbor . The Lateran Treaty between Italy and the Vatican , signed in 1929 , required that the Pope maintain `` perpetual neutrality in international relations '' -- making the Vatican City a neutral state . Several countries suffered invasions in spite of their efforts to be neutral . These included Nazi Germany 's invasion of Denmark and Norway on 9 April 1940 -- then Belgium , the Netherlands , and Luxembourg on 10 May 1940 . On the same day , 10 May 1940 , the British invaded Iceland and established an occupying force ( subsequently replaced by the then - neutral United States ) . In the eastern Baltic , the Soviet Union invaded Lithuania , Latvia and Estonia on 14 June 1940 . In the Balkans , the Italo - Greek War began on 28 October 1940 and Yugoslavia was invaded in April 1941 . Iran was also attacked and occupied by Britain and the Soviet Union in August 1941 .

It was maintained throughout the conflict , in spite of several German air raids ( understood to be by aircraft that missed their intended targets in Britain or Northern Ireland ) and attacks on Ireland 's shipping fleet by Allies and Axis alike . De Valera refrained from joining either the Allies or Axis powers . Portugal ( edit ) Main article : Portugal in World War II Portugal -- Portugal was officially neutral during the World War II . However , it maintained a close relationship with the UK , due to the alliance it had for the last six hundred years , which is the longest lasting military alliance in history . The Estado Novo sought neutrality as a strategy to keep Spain neutral and prevent it from joining the Axis . Portugal continued trading with countries from both sides of the conflict throughout the war . In the second half of the war , it let the Allies use bases in the Azores to fight German submarines , because Salazar feared already an allied invasion over Azores . Colonies of Portugal : Angola Cape Verde Portuguese Guinea Portuguese India Macau Mozambique São Tomé and Príncipe Portuguese Timor ( Occupied by Japan from 1942 to 1944 ) Spain ( edit ) Main article : Spain in World War II Spain -- Franco sent the Blue Division to fight for the Axis on the Eastern Front . Sweden ( edit ) Main article : Sweden during World War II Sweden -- The Swedish government supported Finland during the Winter War . The later transit of German troops through Finland and Sweden and Swedish iron - ore mining during World War II were helpful to Germany . During the Liberation of Finnmark it sent Norwegian `` police '' troops over the border to link up with Allied forces . At the end of the war it was preparing to invade Norway and Denmark with the Allies should the occupying Wehrmacht forces refuse to accept a general German armistice . Switzerland ( edit ) Main article : Switzerland during the World Wars Switzerland -- Switzerland maintained its neutrality so as to protect its own banking interests from plunder by the Axis . It also depended on German coal , with 10 million tons imported during the war , making up 41 % of Swiss energy supplies . Often , Swiss soldiers opened fire on Axis bombers invading their airspace . On several occasions , Switzerland also shot down Allied planes . Throughout the war , cities in Switzerland were `` accidentally '' bombed by both Axis and Allied airplanes . Adolf Hitler did indeed plan to invade Switzerland , but Switzerland had formed complex fortifications and amassed hundreds of thousands of soldiers in the mountains to thwart any Axis invasion . Because of the extreme mountainous conditions in Switzerland , Hitler decided to bombard the United Kingdom rather than engage in a costly war with Switzerland . Lithuania ( edit ) Main article : Resistance in Lithuania during World War II Lithuania -- Lithuania , along with its Baltic neighbours Latvia and Estonia , jointly declared their neutrality on November 18 , 1938 , in Riga , at the Conference of Baltic Foreign Ministers with their respective parliaments passing neutrality laws later that year . Despite that , all three Baltic states were occupied twice by the Soviet Union and once by the Nazi Germany . Latvia ( edit ) Main article : Military history of Latvia during World War II Latvia -- Latvia , along with its Baltic neighbours Lithuania and Estonia , jointly declared their neutrality on November 18 , 1938 , in Riga , at the Conference of Baltic Foreign Ministers with their respective parliaments passing neutrality laws later that year . Despite that , all three Baltic states were occupied twice by the Soviet Union and once by the Nazi Germany . Estonia ( edit ) Main article : Estonia in World War II Estonia -- Estonia , along with its Baltic neighbours Lithuania and Latvia , jointly declared their neutrality on November 18 , 1938 , in Riga , at the Conference of Baltic Foreign Ministers with their respective parliaments passing neutrality laws later that year . Despite that , all three Baltic states were occupied twice by the Soviet Union and once by the Nazi Germany . Microstates ( edit ) Andorra ( edit ) Andorra Liechtenstein ( edit ) Liechtenstein Monaco ( edit ) Monaco ( occupied by Italy and later Germany ) San Marino ( edit ) San Marino ( briefly occupied by Germany , 17 -- 20 September 1944 ; declared war on Germany , 21 September 1944 ) Vatican City ( edit ) Vatican City , see Vatican City in World War II Asia ( edit ) Afghanistan ( edit ) Afghanistan remained neutral throughout World War II . Saudi Arabia ( edit ) Saudi Arabia severed diplomatic contacts with Germany on 11 September 1939 , and with Japan in October 1941 . Although officially neutral , the Saudis provided the Allies with large supplies of oil . Diplomatic relations with the United States were established in 1943 . King Abdul Aziz Al - Saud was a personal friend of Franklin D. Roosevelt . The Americans were then allowed to build an air force base near Dhahran . Saudi Arabia declared war on Germany on 28 February 1945 and Japan on 1 April 1945 , but no military actions resulted from the declaration . Tibet ( edit ) Tibet ( unrecognised ; claimed by China but de facto independent ) , remained neutral throughout World War II Turkey ( edit ) Main articles : Single - party period of the Republic of Turkey § 1938 -- 1950 : İnönü ( National Chief ) , and History of the Republic of Turkey § World War II Turkey was neutral until several months before the end of the war , at which point it joined the Allies . Prior to the outbreak of war , Turkey signed a Mutual Aid Pact with France and Britain in 1939 . After the German invasion of France , however , Turkey remained neutral , relying on a clause excusing them if military action might bring conflict with the USSR , which , after the division of Poland , Turkey feared . Then , in June 1941 , after neighbouring Bulgaria joined the Axis and allowed Germany to move troops through to invade Yugoslavia and Greece , Turkey signed a non-aggression pact with Germany . Turkey was an important producer of chromite -- a key ingredient in the manufacture of stainless steel and refractory brick -- to which the Germans had limited access . Sale of chromite to Germany or to the Allies ( who had access to other sources , and mainly bought Turkish chromite in order to preclude its sale to Germany ) was the key issue in Turkey 's negotiations with both sides . Turkey halted its sales to Germany in April 1944 and broke off relations in August . In February 1945 , after the Allies made its invitation to the inaugural meeting of the United Nations ( along with the invitations of several other nations ) conditional on full belligerency , Turkey declared war on the Axis powers , but no Turkish troops ever saw combat . Yemen ( edit ) Yemen remained neutral throughout World War II Americas ( edit ) Argentina ( edit ) Argentina was ruled during the period of World War II by a series of conservative and military governments . Neutralist feelings prevailed in the military , while sentiment in the population was overwhelmingly pro-Allied . Argentina was traditionally a main economic partner of the United Kingdom , and the main supplier of beef and wheat to the British Isles , and this neutrality allowed shipments to continue unimpeded , provided at generous loans . Thousands of Argentines volunteered for the British armed services , mostly in the No. 164 RAF Argentine squadron , even though Argentina was officially a neutral country during the war . The government of Edelmiro Julián Farrell eventually declared war on Germany and Japan , one month before the war was over in Europe and four months before it was over in Asia , on 27 March 1945 . See also Argentina during World War II . Chile ( edit ) Chile initially chose to remain neutral in the war , having close trading links with Germany . Later in the war , however , Chile distanced itself from the Axis powers , and the Chilean government took steps to dismiss pro-German military officers . Relations with Axis countries were broken in 1943 , and on 11 April 1945 , Chile declared war on Japan , being the last nation to join the war . Throughout the duration of the war , Chile stationed several navy ships around its colony of Easter Island to protect it from a potential Japanese attack against South America . Peru ( edit ) Peru Declared war on 12 February 1945 United States ( edit ) See also : First engagement of neutral United States in World War II before the attack on Pearl Harbor United States -- The United States remained neutral following the outbreak of World War II . However , the sudden defeat of France by Nazi Germany in spring 1940 caused the nation to begin to greatly grow its armed forces , including the first peacetime draft . On December 29 , President Franklin D. Roosevelt declared that the U.S. was to be the `` Arsenal of Democracy '' for the Allied Powers . After the German invasion of the Soviet Union in June 1941 , America began sending Lend Lease aid to the Soviet Union as well as Britain and China . United States non-interventionism remained the nominal policy , as it stayed out of actual fighting until December 8 , 1941 , when it declared war on Japan in response to that country 's surprise attack on Pearl Harbor the previous day . Venezuela ( edit ) Venezuela Declared war on 15 February 1945 . Conclusion ( edit ) Portugal , Spain , Sweden and Switzerland held to the concept of armed neutrality , and continuously amassed soldiers to defend their nation 's sovereignty from potential invasion . Thus , they maintained the right to become belligerent if attacked while in a state of neutrality . The concept of neutrality in war is narrowly defined and puts specific constraints on the neutral party in return for the internationally recognized right to remain neutral . A wider concept is that of non-belligerence . The basic international law covering neutral territories is the Second Hague Convention . It is important to note that a neutral country takes no side in a war between other parties , and in return hopes to avoid being attacked by either of them . A neutralist policy aims at neutrality in case of an armed conflict that could involve the party in question . A neutralist is an advocate of neutrality in international affairs . The concept of neutrality in conflicts is distinct from non-alignment , i.e. , the willful desistance from military alliances in order to preserve neutrality in case of war , and perhaps with the hope of preventing a war altogether . In a study of Spain , Switzerland and Sweden during WWII , Eric Golson found that they engaged in economic realpolitik , as they traded with both the Axis and the Allied Powers .
