President bother S. Truman confronted unprecedented challenges in international affairs during his virtually eight years in office. Truman guided the United states through the finish of civilization War II, the start of the Cold War between the united States and also the Soviet Union, and the dawning that the atomic age. Truman intervened with American troops in the conflict in between North Korea and South Korea and also he supported the development of the state that Israel in the middle East. In sum, Truman"s international policy developed some of the basic principles and commitments that marked American foreign policy because that the remainder that the twentieth century.
You are watching: President truman’s chief priority in using the atomic bomb against japan was to _____.
Truman inherited Roosevelt"s national security team, despite he would certainly transform it—in regards to both personnel and also organization—during the food of his presidency. In ~ the State Department, Truman changed FDR"s last secretary the state, Edward Stettinius, with previous senator, can be fried Court justice, and war mobilization manager James F. Byrnes. Byrnes tackled the opened rounds of negotiation at the postwar conferences of allied international ministers, yet he proved problematic because that the President. Truman changed him in 1947 through Gen. George C. Marshall, military chief of staff during the war, who had actually attempted to mediate the Chinese civil war during 1946. Marshall, in turn, was flourished by Dean G. Acheson, a previous undersecretary that state, in 1949. Marshall and also Acheson proved influenced leaders and sometimes brilliant architects of joined States international policy.
Truman additionally reorganized the nation"s military and also national defense apparatus with passage that the nationwide Security plot in 1947. The legislation had three main purposes. It merged the Army, Navy, and also Air force under a national Military facility (NME) headed by a civilian Secretary the Defense. 2 years later, the NME to be renamed the room of Defense and also made an executive department. The national Security Act also created the main Intelligence Agency, the leading eight of the nation"s knowledge network. Finally, the Act created the nationwide Security board of directors (NSC) to advise the president on problems related primarily to American foreign policy. If underdeveloped and undernourished throughout its very first years of existence, the NSC thrived in prestige and also power as result of U.S. Authorized in the oriental War. End the coming decades, the NSC became a significant instrument the American foreign policy.Entering the atom Age
When Truman ascended come the presidency on April 12, 1945, human being War II in Europe was nearly over; in ~ a month, Hitler cursed suicide and Germany surrendered. In the Pacific, however, the end of the war with Japan seemed farther away. Together Truman took office, armed forces planners guess that full victory would require an Allied invasion of Japan. The invasion would likely extend the battle for at least an additional year and also cost, by one estimate, end 200,000 American casualties.
Truman knew that an additional option can exist. The top-secret Manhattan task was at work-related on an atomic bomb, a an equipment that among the President"s advisers defined "as the most destructive weapon ever known in human history." if attending the Potsdam summit in July, Truman learned that a check of the bomb had actually been successful. The possibility of bringing the war to an earlier conclusion was exceedingly attractive; the added heft this brand-new weapon can give come perceptions that U.S. Power, when hardly determinative, likewise weighed top top the President"s mind. With numbers for a full-scale intrusion of the Japanese residence islands mounting and Japanese leaders offering couple of concrete ideas of agreeing to the President"s terms because that unconditional surrender, Truman endorsed the use of the bomb against Japan.
On the morning of respectable 6, 1945, the B-29 bomber Enola happy dropped an atomic bomb ~ above Hiroshima, Japan. Approximates of the casualties room notoriously slippery, but upwards that 100,000 people, perhaps—mostly civilians—perished instantly. Two days later, hearing no word indigenous the Japanese federal government (which was in deep negotiations around whether to surrender), Truman permit the U.S. Armed forces proceed through its plans to drop a second atomic bomb. On august 9, that weapon fight Nagasaki, Japan. The Japanese agreed come surrender on respectable 14 and then walk so, much more formally, top top September 2. Human being War II to be over.Problems through the Soviet Union
Even before the finish of world War II, tensions between the Soviet Union and the unified States began to mount as both countries looked to form the post-war international order in line with their interests. One of the most necessary flashpoints to be Poland. At the Yalta conference in February 1945, the Soviet Union i agree in basic terms come the establishment of freely chosen governments in newly liberated locations of east Europe. Never ever fulfilling this promise, it developed a polish Communist-dominated puppet government in the feather of 1945 as the an initial of what would later end up being its east European satellites.
Truman hoped the the united States and the U.S.S.R. Could maintain amicable relations, though he realized that conflicts would for sure arise between the globe"s most an effective nations. He thought that tough-minded negotiation and also the occasional compromise would allow the united States however to achieve a modus vivendi favorable to American interests. A couple of of Truman"s advisers dissented from also this guarded approach. Citing the situation in Poland, castle warned that the Soviets would try to dominate as lot of Europe as possible.
At Potsdam in July 1945, Truman met face-to-face through Soviet leader Josef Stalin and also British element minister Winston Churchill. The conference moved gradually and resolved little. Stalin re-iterated his earlier pledge to get in the war in the Pacific versus Japan—an sell Truman conveniently accepted—but American efforts to diminish Soviet affect over eastern Europe went nowhere. Nonetheless, as the conference pertained to an end, Truman created to Bess, "I prefer Stalin . . . The is straightforward. Knows what he wants and will compromise when he can"t get it."In the comes months and also years, Truman would readjust his opinion. Potsdam had actually been a personal success because that Truman—he appeared to get along with his fellow heads of state—but the inability to settle superior issues, such together the future of Germany, the boundaries of postwar Poland, and also the nature that wartime reparations hinted at major underlying differences in between the two nations. Secretary that State Byrnes make the efforts in vain to occupational with the Soviets v the last months that 1945 and also into beforehand 1946, despite without lot success. In ~ the very same time, the Soviets tightened their regulate over east Europe and also attempted to extend their influence into Turkey and Iran. The United states blunted Soviet intentions in those two countries through diplomacy and a show of military strength. Stalin heightened tensions v a fiery speech in February 1946, predicting a comes clash v capitalism.The early on Cold War
Each the these breakthroughs frustrated and also worried American leaders. Truman told Byrnes in January 1946, "I"m exhausted babying the Soviets." others agreed. In February, George F. Kennan, the momentary head of the American embassy in Moscow, sent out his assessment of Soviet foreign policy to Washington in what became known as the "long telegram." Kennan suggested that the Soviets, urged by a mix of Marxist-Leninist ideology and also traditional Russian security concerns, were bent ~ above expansion and were irrevocably opposed to the joined States and the West, and also to capitalism and democracy. The urged American leader to confront and also contain the Soviet threat. 2 weeks later, former British prime minister Winston Churchill, speaking in Fulton, Missouri, declared that the Soviets to be bringing one "iron curtain" down across Europe—and the the unified States and Britain necessary to intensely oppose Soviet expansionism. Kennan"s analysis gave American public official a frame for understanding the Soviet challenge, Churchill"s formulation brought the threat home to the public at-large.
Relations in between the 2 nations ongoing to worsen in 1946. Britain got a $3.75 exchange rate loan indigenous the U.S. Government to help it rebuild. In Stuttgart, Germany, Secretary of State Byrnes cursed the United states to the reconstruction of that nation both economically and also politically—and promised to save troops there as lengthy as necessary. These 2 decisions hinted at an arising worldview amongst government policymakers: American understanding required an ext active security from Soviet encroachment. It came as small surprise, then, once Truman dismissed Secretary of commerce Henry Wallace in September 1946 after ~ Wallace offered a decided repudiating the administration"s anti-Soviet international policy.
America sharpened its strategy toward the U.S.S.R. In 1947. The President and also his advisers grew much more concerned that west europe nations, quiet reeling from the devastation wrought by world War II, might elect aboriginal Communist federal governments that would orient their nations—politically, economically, and militarily—toward the Soviet Union. Moreover, after the British federal government told American officials that it might no much longer afford to serve as the watchdog that the eastern Mediterranean, Truman announced in in march 1947 what became known as the Truman Doctrine. He pledged U.S. Support for the pro-Western federal governments of Greece and also Turkey—and, by extension, any likewise threatened government—arguing that the joined States had a duty to support "free peoples who are resisting test subjugation by armed minorities or by outside pressures." In the summer the 1947, Secretary that State George Marshall announced a multi-billion dollar assist program for Europe, which came to be known together the Marshall Plan, the he hoped would encourage both political and economic stability and also reduce the attraction of communist to Europe"s enduring populations.
In 1948, the last pieces the the Cold war chessboard started to autumn into place. In February, Soviet-backed communists seized manage of Czechoslovakia, the last continuing to be independent democracy in east Europe. In March, the Truman administration won conference approval the the Marshall Plan. And also throughout the spring and summer, the unified States, England, and also France—each occupying a zone the Germany—accelerated the procedure of merger those regions right into a separate country that, by 1949, would become West Germany. The Soviets comment by blockading western accessibility routes come Berlin which, when in your zone, to be administered together by all four powers. Truman, determined not to abandon the city, ordered an airlift that food and also fuel to break the blockade.
The Berlin stand-off it s long until may 1949, when the Soviets referred to as off the blockade in return for a conference ~ above the future the Germany. The meeting finished in failure after Stalin refused a U.S. And also British offer to make the Soviet zone component of a democratic, combined Germany; the nation would continue to be divided in between West and also East until October 1990. Simply as important, the February 1948 Communist coup in Czechoslovakia and also the Soviet-American confrontation end Berlin spurred the production of one alliance, largely on the invite of europe statesmen, in between the unified States, Canada, and also Western Europe—what came to be known together the phibìc Atlantic treaty Organization, or NATO—to counter Soviet power. By mid-1949, Europe was divided politically, economically, militarily, and ideologically.
That year also significant the end of the U.S. Nuclear monopoly. Truman had actually hoped that in the wake up of Hiroshima and also Nagasaki, the advancement of atomic energy (for both peaceful and also martial uses) would be put under U.N. Control. In beforehand 1946, the Soviets rejected the U.S.-sponsored plan, i m sorry would have actually left the American atomic monopoly in place. Instead, the Kremlin redoubled its efforts to construct a bomb which, v the aid of atomic espionage, pertained to fruition much an ext quickly 보다 American policymakers and intelligence experts ever before predicted.
Moscow"s successful test of an atomic weapon in the late summer of 1949 required the Truman management to re-evaluate its nationwide security strategy. Truman decided in January 1950 to authorize the advancement of an even more powerful weapon—the hydrogen bomb—to respond to the Soviets, thus accelerating the Cold war arms race. In September, Truman approved a nationwide Security council document—NSC-68—that reevaluated and also recast American armed forces strategy. Amongst other things, NSC-68 stressed the need for a huge buildup of conventional and also nuclear forces, no issue the cost. Truman greeted NSC-68, and its military and economic implications, through ambivalence, despite the battle in Korea, which began in the summer that 1950 and also made the risk of armed difficulty from the U.S.S.R. Seem real and also perhaps immediate, caused a much more rapid implementation that the document"s findings.The united Nations
In the years after world War II, Truman worked diligently to assure that the united Nations—conceived by president Franklin D. Roosevelt together a forum in i m sorry differences between nations could be resolved prior to they resulted in war - would certainly be a significant player in global life. Because that the many part, he succeeded.
The new President sent out a bipartisan delegation to the joined Nation"s starting conference in san Francisco in mid-1945, believing it necessary that both the the significant American political next endorse the organization. The significant roadblock to the development of the United nations came indigenous the Soviets, who were sluggish to join. Truman managed to secure your participation after sending out special emissary harry Hopkins to Moscow. Some Americans would later argue, however, the the price of that participation—American acquiescence to a reorganized Polish government allied through the Soviets—was as well steep. Nonetheless, the mountain Francisco Conference adjourned in June 1945 after ~ its participating nations, including the Soviets, signed the starting U.N. Charter.
The unified Nation"s most far-reaching accomplishment during the Truman years came during the korean War. In the wake up of phibìc Korea"s invasion of southern Korea, the U.N. Protection Council met, officially condemned phibìc Korea"s aggression, and pledged armed forces support to southern Korea. Though the unified States provided most that the U.N. Troops that battled in the battle alongside the southern Koreans, these pressures were component of a multilateral effort. The Soviet Union, a member that the defense Council, might have vetoed U.N. Involvement in the war were it not for their boycott the the meeting; Moscow was protesting the U.N."s fail to chair a representative the the freshly established—and communist—People"s Republic of China.Success and also Failure in Asia
In Japan, i m sorry the united States lived in at the conclusion of human being War II, basic Douglas MacArthur managed a Japanese financial recovery and also political reformation. Japan"s new constitution take it its cues native the ideals embodied in the American constitution. Through the start of the oriental War, the Japanese economy started its slow and steady climb to prominence, peaking in the 1980s.
The united States and also the Truman administration proved less successful in shaping China"s politics future. In the wake up of world War II, civil war resumed between supporters of nationalist Chinese leader Jiang Jieshi and the pressures of Communist leader Mao Zedong. Truman sent general George C. Marshall come China in 1946 in an eventually unsuccessful attempt to mediate the problem and form a coalition government. The management determined privately the no quantity of American assist could save Jiang, the western Europe more urgently compelled U.S. Funding, and also that the triumph the Mao"s forces would no be terrible to American interests. By respectable 1949, the State department would concern a "white paper" outlining the administration"s position on China and the reasons for the comes communist victory.
Two months later, top top October 1, 1949, Mao declared the founding of the People"s Republic that China. V Jiang"s pressures in full retreat to the island of Formosa, the President and his advisers confronted the firestorm in American politics touched turn off by the Chinese Communist victory. Republic in Congress, including a group who want to reorient American foreign policy away from Europe and also toward Asia, howled that the Truman management had "lost" China. After Mao and also Stalin i agree in at an early stage 1950 to a mutual defense treaty, critics of the administration"s China policy redoubled their attacks. In this era the the Red Scare—Senator Joseph McCarthy leveled his infamous allegations concerning communists in the State department in February 1950—the "loss" the China constituted a damning political charge.The korean War
Truman"s problem in Asia explosive on the oriental peninsula. In the wake of people War II, Korea had actually been partitioned in ~ the 38th parallel, with the Soviets supporting a communist regimen north of the boundary and the americans a non-communist one in the south. ~ above June 25, 1950, phibìc Korea released a surprise intrusion of south Korea. The united Nations instantly condemned phibìc Korea, if Truman and his advisers in Washington discussed the American response. Specific that the Soviet Union lay behind the invasion, lock reasoned that failure come act would lead U.S. Allies to concern America"s meeting to resist Soviet aggression. Truman fixed not to repeat the failure of Munich, whereby the European powers appeased and condoned Hitler"s expansionism. Scholar now know that the invasion was the brain-child the North korean leader Kim Il-sung and that Stalin acceded come it only after do clear that the Soviets themselves would not become connected militarily and also that Mao provide ground troops. Ultimately, the Soviets did carry out the phibìc Koreans through air support.
Truman ordered the American military, under the direction of general Douglas MacArthur, to intervene. The an initial U.S. Troops did tiny to stop the onslaught as North Korean pressures made rapid progress in your march down the peninsula. Through August, the Americans were holed-up in a defensive perimeter top top the southeastern reminder of south Korea. MacArthur released an audacious and also risky counter-attack the complying with month that featured an amphibious landing behind foe lines in ~ Inchon ~ above the western coast of southern Korea, close to the resources of Seoul.
MacArthur"s gamble worked; American pressures rapidly drive the phibìc Koreans back to the border in ~ the 38th parallel. MacArthur then obtained permission native the Truman administration to cross the border come secure the final defeat of north Korea and also the reunification of the country. The danger, though, was obvious. The Soviet Union and also China both bordered phibìc Korea and also neither want an American-led armed forces force, or one American ally, on your doorsteps. In mid-October, meeting v the chairman at wake up Island, MacArthur said Truman the there to be "very little" possibility of Chinese or Soviets intervention. At the same time, however, the Chinese warned American officials though third-party governments that castle would get in the war if the United states crossed the 38th parallel.
Disregarding these warnings, American pressures pushed northward throughout October and also into November 1950, coming to within several miles of the Chinese border. The Chinese entered the fight in late November, launching a enormous counter-attack the threw the Americans ago south of the 38th parallel; an American an answer in the feather of 1951 thrust the front phibìc to the 38th parallel, the standing quo antebellum. A brutal and bloody dead end ensued for the following two years as peace talks relocated forward in fits and also starts.
American authorized in Korea lugged Truman an ext problems than successes. After general MacArthur publicly tested the administration"s army strategy in the feather of 1951, Truman fired him. MacArthur returned house a hero, however, and Truman"s popular plummeted. Versus the background of McCarthyism, the fail to attain military victory in Korea allowed Republicans to attack Truman mercilessly. Indeed, the war so badly eroded Truman"s politics standing that the President"s slim chances of winning i of his "Fair Deal" domestic legislation disappeared altogether.
Despite these setbacks, Truman"s decision come stand and also fight in Korea to be a landmark event in the at an early stage years of the Cold War. Truman reassured America"s europe allies the the U.S. Commitment come Asia would not come in ~ Europe"s expense—a commitment made an ext tangible in 1951 by increased American troop deployments come Europe and also not Korea. The President thus guaranteed the United claims to the defense that both Asia and also Europe indigenous the Soviet Union and its allies. Likewise, the korean War locked in the high level of defense spending and also rearmament referred to as for by NSC-68. Finally, the American effort in Korea was accompanied by a serious financial commitment to the French defense the a non-communist Indochina. In a very real sense, Korea militarized the Cold War and also expanded its geographical reach.The development of Israel
Between 1945 and 1948, Truman wrestled through the Jewish-Arab trouble in British-controlled Palestine. Britain had actually searched because that a systems to the conflict between Palestine"s Jewish minority and Arab majority since the end of the an initial world war, but with tiny success; Arabs continuously rejected the British tip that a Jewish "national home" be created in Palestine. In February 1947, the british government, straining come uphold the other royal commitments and with its soldiers continually under attack by Jewish militias, announced that would shortly pass manage of Palestine to the joined Nations. The united Nations, in respectable 1947, proposed to partition Palestine into two states, one because that an Arab majority and one because that the Jewish minority. Jews, by and also large, embraced this solution, when Arabs vigorously opposed the plan, as they had actually for the coming before decades. The prospect of partition ignited a savage and also destructive guerilla war between Arabs and Jews in Palestine.
The concern Truman challenged was whether to expropriate the U.N. Partition plan and the creation of a Jewish state. While Truman personally sympathized through Jewish aspirations for a homeland in the middle East, the issue associated both domestic and foreign concerns. The President and also his political advisers were very aware that American Jews, a major constituency in the autonomous Party, sustained a state for your co-religionists in the middle East. In an election year, Democrats could ill bought to lose the Jewish poll to Republicans. Top top the other hand, Truman"s foreign policy advisers, especially Secretary of State Marshall, counseled strongly versus American support for a Jewish state. They worried the such a course was particular to fury the Arab claims in the region and can require an American army commitment. Together at the very least one high-ranking Defense Department official argued, access to oil, not the development of a Jewish homeland, was America"s priority in the middle East.

In November 1947, Truman bespeak the American delegation at the United nations to support the partition plan. In the following months, though, administrative battles amongst presidential advisers over the wisdom that the setup intensified, and also Truman apparently lost control of the policy-making process. He finished up endorsing a plan—by mistake, apparently—that would have created the Jewish state as a United countries trusteeship, quite than as an autonomous entity. Truman back-tracked furiously from his remark, though without clarifying U.S. Intentions. Occasions in Palestine required the President"s hand, however. The army triumph of Jewish nationalists over your Arab adversaries in the guerilla battle made it clear the the Israeli nation would soon come right into being. On might 15, the united States, in ~ Truman"s direction, became the first country to recognize the state the Israel.
