Since the late 1990s, Article 9 has been the central feature of a dispute over the ability of Japan to undertake multilateral military commitments overseas. During the late 1980s, increases in government appropriations for the JSDF averaged more than 5% per year. By 1990 Japan was ranked third, behind the then-Soviet Union and the United States, in total defense expenditures, and the United States urged Japan to assume a larger share of the burden of defense of the western Pacific. (Japan has a guideline of a limit of 1% of GDP on defense spending; however, Japan defines a number of activities as non-defense spending.) Given these circumstances, some have viewed Article 9 as increasingly irrelevant. It has remained, however, an important brake on the growth of Japan's military capabilities. Despite the fading of bitter wartime memories, the general public, according to opinion polls, continued to show strong support for this constitutional provision.
