It said, "having recommended that the members of the United Nations furnish such assistance to the Republic of Korea as may be necessary to repel the armed attack and to restore peace and security in the area." .
Despite this support, America's Korean campaign was unsuccessful, this was to some degree the fault of President Truman, who had not believed that the Chinese government would be prepared to intervene and he also underestimated the military power of China. Therefore, not wanting to engage in an all-out war with China and the Soviet Union, which would most likely have led to the Third world war, Truman was forced to negotiate, and thus the Korean War ended in stalemate on July 1953 after long negotiations for peace a cease-fire was finally signed. However it is an uneasy peace and to this day the two Korean nations have not reunified. Most South Koreans believe that the North are "engaged in a deceptive peace offensive in a bid to cover up their aggressiveness by misleading world opinion" .
America too keeps a watchful eye on North Korea, knowing that this communist country has nuclear capability. .
The Vietnam War commenced very differently from Korea, the Korean War originated internally when North attacked South, but Vietnam was started externally by the United States. "In August 1964, on the pretext of a North Vietnamese attack on U.S naval craft off the North Vietnamese coast, Johnson ordered air attacks on communist military instalments along the northern coast" .
Vietnam commenced under the shadow of Koreas failure, the presidents reigning during this period feared the political views which may have been taken had they settled for a stalemate such as in Korea, losing Vietnam .
The Vietnam War brought an end to the domestic support towards U.S. cold war policy, this war was not supported by either the UN or domestically. "the war was lost primarily at strategic, diplomatic, and domestic political levels" .
