<P> The Korean War was the last major conflict Canadian forces participated in until the 1991 Persian Gulf War, and the last major combat by ground troops until 2002 in Afghanistan . Canada played a minor role in the fighting in Cyprus in 1974 and in the Balkans at Medak Pocket in the 1990s . </P> <P> The Canadian military was revitalized as a result of the Korean War . A changeover to U.S. - designed weapons and equipment had been planned for the 1950s, but the emergency in Korea forced the use of war stocks of British - designed weapons from World War II . In the late 1950s, Canada adopted a variety of weapons of both European and U.S. design rather than proceeding with its planned Americanization . </P> <P> Japan was politically disturbed both from the security threat to Japan because of the initial defeat of South Korea and from left - wing activities in support of North Korea and aiming to bring about a communist revolution in Japan . Additionally, as American occupation armies were dispatched to Korean peninsula, Japan's security became problematic . Under United States guidance, Japan established Reserved Police, later the Japan Self - Defense Forces (自衛隊). The signing of the Treaty of Peace with Japan (日本 国 と の 平和 条約; popularly known as the Treaty of San Francisco) was also hastened to return Japan back into international communities . In the eyes of some American policy makers, the non-belligerency clause in the Constitution was already being considered a "mistake" by 1953 . </P> <P> Economically, Japan was able to benefit vastly from the war, and the Korean War greatly helped the rise of Japan's economy and its development into a world power . American requirements for supplies were organized through a Special Procurements system, which allowed for local purchases without the complex Pentagon procurement system . Over $3.5 billion was spent on Japanese companies, peaking at $809 million in 1953, and the zaibatsu went from being distrusted to being encouraged . Among those who thrived not only on orders from the military but also through American industrial experts, including W. Edwards Deming were Mitsui, Mitsubishi, and Sumitomo . Japanese manufacturing grew by 50% between March 1950 and 1951, and by 1952, pre-war standards of living were reached and output was twice the level of 1949 . Becoming an independent country after the Treaty of San Francisco saved Japan from the burden of expense of the occupation forces . </P>
