<u><em> Relations between the Soviet Union and the United States were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. The distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the Cuban missile crisis, brought them to the brink of war. </em></u>
<u><em> </em></u>
<u><em>The United States government was initially hostile to the Soviet leaders for taking Russia out of World War I and was opposed to a state ideologically based on communism. Although the United States embarked on a famine relief program in the Soviet Union in the early 1920s and American businessmen established commercial ties there during the period of the New Economic Policy (1921–29), the two countries did not establish diplomatic relations until 1933. By that time, the totalitarian nature of Joseph Stalin's regime presented an insurmountable obstacle to friendly relations with the West. Although World War II brought the two countries into alliance, based on the common aim of defeating Nazi Germany, the Soviet Union's aggressive, antidemocratic policy toward Eastern Europe had created tensions even before the war ended. </em></u>

<u><em>The Soviet Union and the United States stayed far apart during the next three decades of superpower conflict and the nuclear and missile arms race. Beginning in the early 1970s, the Soviet regime proclaimed a policy of détente and sought increased economic cooperation and disarmament negotiations with the West. However, the Soviet stance on human rights and its invasion of Afghanistan in 1979 created new tensions between the two countries. These tensions continued to exist until the dramatic democratic changes of 1989–91 led to the collapse during this past year of the Communist system and opened the way for an unprecedented new friendship between the United States and Russia, as well as the other new nations of the former Soviet Union.</em></u>
<u><em>After the Bolshevik Revolution of 1917, the ensuing Civil War produced acute food shortages in southwestern Russia. Wartime devastation was compounded by two successive seasons of drought, and by 1920 it was clear that a full-scale famine was under way in the Volga River Valley, Crimea, Ukraine, and Armenia. Conditions were so desperate that in early 1920 the Soviet government sent out a worldwide appeal for food aid to avert the starvation of millions of people. </em></u>
<u><em> </em></u>
<u><em>Several volunteer groups in the United States and Europe had by then organized relief programs, but it became clear that help was needed on a larger scale because an estimated 10 to 20 million lives were at stake. Although it had not officially recognized the Soviet regime, the United States government was pressed from many sides to intervene, and in August 1920 an informal agreement was negotiated to begin a famine relief program. In 1921 President Warren Harding appointed Herbert Hoover, then secretary of commerce, to organize the relief effort. </em></u>
<u><em> </em></u>
<u><em>Congress authorized $20 million, and Hoover proceeded to organize the American Relief Administration (ARA) to do the job. Under Hoover's terms, the ARA was to be a completely American-run relief program for the transport, storage, and delivery of relief supplies (mainly food and seed grain) to those in the famine region. After Soviet officials agreed, hundreds of American volunteers were dispatched to oversee the program. The ARA gradually earned the trust of the local Communist authorities and was given a virtually free hand to distribute thousands of tons of grain, as well as clothing and medical supplies. This remarkable humanitarian effort was credited with saving many millions of lives. </em></u>
<u><em> </em></u>
<u><em>ARA aid continued into 1923, by which time local farms were again producing and the famine's grip was broken. Hoover and his ARA were later honored by the Soviet government for the care and generosity that the United States had shown in this desperate crisis.</em></u>Answer:
