On Dec. 31, 1946, President Truman
declared an end to the period of World War II hostilities. Early in 1947 the
British said they could not support the Greek government after March 31. Many
diplomats feared that the Soviet Union would then spread its power throughout
the Middle East. President Truman met the problem by asking Congress for 400
million dollars to aid Greece and Turkey to prevent the rise of communist
governments. Congress approved the money. This policy of aid, popularly known
as the Truman Doctrine, was an American challenge to Soviet ambitions
throughout the world. As U.S. efforts to check Soviet power around the world
grew, this doctrine evolved into a more general effort, commonly referred to as
“containment policy”.
The
victorious Allies of World War II divided Germany into occupation zones: the
American, French, and British zones in the west and a Soviet zone in the east.
Within the Soviet zone lay Berlin, formerly Hitler’s capital, also divided into
four sectors, each administered by one of the wartime allies. The only
guaranteed way to get to isolated Berlin was by air. The Soviet Union had
granted each of the three Western Allies a 20-mile-wide air corridor leading
from their respective occupation zones to the city; but no such arrangement
controlled travel by road or rairoad--that depended upon the continuing
cooperation of Soviet authorities.
Scarcely
had the war ended when relations between the Western Allies and the Soviet
Union began to deteriorate. Eastern Europe came under Soviet domination. As
early as 1946, Britain’s wartime Prime Minister, Winston Churchill, in a speech
in Fulton, Missouri, warned: "From Stettin on the Baltic to Trieste in the
Adriatic, an iron curtain has descended across the continent." Behind that
curtain, Soviet control tightened; a sphere of influence became a ring of
satellite states, as happened to Czechoslovakia in February 1948 when a
Communist faction seized control of the government. Shortly afterward, the
Soviet Union began exerting pressure on the overland routes leading into
Berlin, imposing restrictions on access, such as temporarily halting coal
shipments and, on 24 June, establishing a blockade.
