Korean
War History
The invasion of South Korea by North Korea came as a
complete surprise to the US; Dean Rusk of the State Department had told
Congress on June 20 that no war was likely. However, a CIA report in
early March had predicted a June invasion. US officials had previously
publicly stated that America would not fight over Korea, and that the
country was outside of American concern in the Pacific. This attitude
may have encouraged the North or given Syngman Rhee in the South a
motive to gain US support.
On hearing of the invasion, Truman agreed with his
advisors to use US air strikes, unilaterally, against the North Korean
forces. He also ordered the Seventh Fleet to protect Formosa. The US
gained a United Nations mandate for action because the Soviets were
boycotting the Security Council while the (Nationalist controlled)
Republic of China held the Chinese seat. Without the Soviet veto and
with only Yugoslavia abstaining, the UN voted to aid South Korea.
The US would have fought whatever the outcome, and
Douglas MacArthur later told Congress "I had no connection with the UN
whatsoever". US forces were eventually joined during the conflict by
troops from fifteen other UN members: Australia, New Zealand, the United
Kingdom, France, Canada, South Africa, Turkey, Thailand, Greece, the
Netherlands, Ethiopia, Colombia, the Philippines, Belgium, and
Luxembourg. (Truman would later take harsh criticism for not obtaining a
declaration of war from Congress before sending troops to Korea. Thus,
"Truman's War" was said by some to have violated the spirit, if not the
letter, of the United States Constitution.)
The US forces were suffering from demobilization which
had continued since 1945. Excluding the Marines, the infantry divisions
sent to Korea were at 40% of paper strength, and the majority of their
equipment was found to be useless.
The Americans organized Task Force Smith, and on July 5
engaged in the first North Korean/American clash of the war.
In initial stages of the war, North Korea's troops
overwhelmed South Korean forces and drove them to a small area in the
far South around the city of Pusan. This became a desperate holding
action called the Pusan Perimeter. Upon the entrance of US and UN
forces, American General Douglas MacArthur, as UN commander in chief for
Korea, ordered an invasion far behind the North Korean troops at Inchon.
United Nations troops drove the North Koreans back past the 38th
parallel and continued on toward the Yalu River border of North Korea
and China. This brought the communist Chinese into the war.
The communist Chinese had issued warnings that they would
react if the UN forces encroached on the frontier at the Yalu River. Mao
sought Soviet aid and saw intervention as essentially defensive. "If we
allow the US to occupy all of Korea... we must be prepared for the US to
declare... war with China", he told Stalin. Zhou Enlai was sent to
Moscow to add force to Mao's cabled arguments.
Mao delayed his forces while waiting for Russian help,
and the planned attack was thus postponed from 13 October to 19 October.
Soviet assistance was limited to providing air support no nearer than
sixty miles (96 km) to the battlefront. The MiG-15s in PRC colors were
an unpleasant surprise to the UN pilots; they held local air superiority
against the F-80 Shooting Stars until the newer F-86 Sabers were
deployed. The Soviet role was known to the US but they kept quiet as to
avoid any international and potential nuclear incidents.
A Chinese assault beginning on October 19, 1950, under
the command of General Peng Dehuai with 380,000 People's Liberation Army
troops repelled the United Nations troops back to the 38th parallel, the
pre-conflict border. The Chinese assault caught US troops by surprise,
as war between PRC and the United States had not been declared. The
United States XX Corp retreat was the longest retreat of a US unit in
history. The Marines, on the northern side of the peninsula, faired
better, mainly due to better training and discipline.
On January 4, 1951, communist Chinese and North Korean
forces captured Seoul. The battle of Chosin Reservoir in winter was a
terrible defeat for the United Nations troops, who were mainly American
Marines. The situation was such that MacArthur mentioned that atomic
weapons may be used, much to the alarm of American allies.
MacArthur was removed from command by President Harry S.
Truman in 1951. The reasons for this are many, and well documented. They
include MacArthur meeting with Chiang Kai-shek in the role of a US
diplomat. MacArthur also was wrong at Guam when President Truman asked
him specifically about Chinese troop buildup near the Korean border.
Furthermore, MacArthur openly criticized the Commander in Chief during
press conferences. He also was rude, and flippant when speaking to
Truman.
The rest of the war involved little territory change and
lengthy peace negotiations (which started in Kaesong on July 10 of the
same year). A cease-fire established a demilitarized zone (DMZ) around
the 38th parallel, which is still defended today by North Korean troops
on one side and South Korean and American troops on the other. No peace
treaty has yet been signed, fifty years later. Newly-elected US
President Dwight D. Eisenhower on November 29, 1952 fulfilled a campaign
promise by traveling to Korea to find out what could be done to end the
conflict.
Korea was officially a police action, not a war, in US
parlance. 600,000 Koreans had died and perhaps a million Chinese. US
troops suffered about 50,000 fatalities, roughly equal to the Vietnam
conflict, but in a much shorter time. Later neglect of remembrance of
this war, in favor of the Vietnam War, World War I and II, has caused
the Korean War to be called the Forgotten War or the Unknown War.
The war was instrumental in re-energizing the US
military-industrial complex from their post-war slump. The defense
budget was boosted to $50 billion, the Army was doubled in size, as was
the number of Air Groups, and they were deployed beyond American soil in
Europe, the Middle East and elsewhere in Asia, including Vietnam, where
covert aid to the French was made overt. The Cold War became a much
stronger state of mind for American policy makers.
Japan was a key beneficiary of the war. The US material
requirements were organized through a Special Procurements system, which
allowed for local purchasing without the complex Pentagon procurement
system. Over $3.5 billion was spent with Japanese companies, peaking at
$809 million in 1953, and still significant in 1955. Other foreign
non-military investment was less than 5% of this.
US Aid Counterpart Funds gave Japan, by 1956, the most
modern shipyards in the world and a 26% share in launched tonnage.
Left-wing organizations were closed down, and the zaibatsu went from
being distrusted to being encouraged - Mitsui, Mitsubishi and Sumitomo
were amongst the zaibatsu that thrived, not only on orders from the
military but through American industrial experts, including W. Edwards
Deming. Japanese manufacturing grew by 50% between March 1950 and 1951.
By 1952, pre-war standards of living were regained and
output was twice the level of 1949. The 1951 peace treaty returned
Japanese sovereignty (excluding Okinawa and the Ryukyu islands) and the
non-belligerency clause in the constitution was being considered a
"mistake" by 1953.

Korean War Summary
Koreans welcomed the defeat of Japan in World War II with
great joy and relief. However, their joy was short-lived. Liberation did
not bring the independence for which the Koreans had fought so hard, but
the inception of ideological conflict in a divided country.
The efforts of the Koreans to establish and independent
government were frustrated by the United States in the South and the
occupation of the North by the Soviet Union.
In November 1947, the United Nations General Assembly
adopted a resolution which called for a general election under the
supervision of the UN Commission. However, the Soviet Union refused to
comply with the UN resolution and denied the UN Commission access to the
northern part of Korea. The UN Assembly adopted a new resolution calling
for elections in areas accessible to the UN Commission.
The first elections in Korea took place on May 10, 1948,
in the area south of the 38th parallel, and the government of the
Republic of Korea was inaugurated on August 15,. A Communist regime was
set up in the North under Kim Il-sung, a Stalinist ruler with absolute
power.
On June 25, 1950, North Korea launched an unprovoked
full-scale invasion of the South and started a war that lasted three
years. As the Communist North Koreans campaigned to unify the country by
force, the entire land was devastated and millions of people were left
homeless and separated from their families. A cease-fire was signed in
July 1953, and both sides have since gone through enormous changes in
their efforts at rehabilitation.
Reunification remains the long-cherished but elusive goal
of all Koreans on both sides of the vigilantly guarded Military
Demarcation Line. The fall of Communism in the Soviet Union and Eastern
Europe and the unification of Germany raised expectations in Korea the
unification could be achieved in the not very distant future.
Some progress in promoting trust and cooperation between
the two halves of the peninsula was made in recent years. However, the
threat of North Korea's suspected nuclear weapons development program
has stood in the way of real forward movement, and there is still a long
bumpy road before the proposed Korean Peninsula Energy Development
Organization (KEDO) project for the construction of light water nuclear
reactors gets under way in the North and other North Korean nuclear
issues are completely settled.

Mark Clark assumed command of U.N. forces in Korea, on May 12,
1952, he was confronted with a military deadlock on the front
lines, stalled Armistice negotiations, and a violent prisoner of
war situation on the island of Koje-do, off the southern coast
of South Korea. Clark believed that the Communists only
understood force and stepped up military pressure on the enemy
to break the stalemate at Panmunjom. |
