the 9th Article of the Constitution

Since North Korea's nuclear test in July disturbed Japanese people, Article 9 of the Constitution is now a controversial issue again in Japan. Article 9 of the Constitution: 1. Aspiring sincerely to an international peace based on justice and order, the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as means of settling international disputes. 2. In order to accomplish the aim of the proceeding paragraph, land, sea, and air forces, as well as other war potential, will never be maintained. The right of belligerency of the state will not be recognized. (Source of info: Wikipedia) The 9th article of the Constitution of Japan is very beautiful which every country in the world should follow in the future. However, Japanese government has changed its interpretation so many times to legalize the Japanese Self-Defence Forces because the situation has greatly changed after the World War 2. Some people say that the article 9 should be revised so that the Self-Defence Forces will be legally permitted (realistic), while others say that the article 9 shoudn't be revised (idealistic). This issue is very complicated and I can't write down all the information here. But in my opinion, the article 9 shouldn't be revised. The article was originally made by American people but this has been worked pretty well for the democracy of Japan. The Self-Defence Forces should help people in trouble to play an improtant role in the international community, but they shouldn't be involved in war. The other day, Rice (U.S. Secretary of State) visited Japan and confirmed that Japan is under the U.S. nuclear umbrella to show that Japan is secured by the U.S. Costa Rica has never had standing army. Why don't we promote our way of thinking to the world in the long run to achieve the world peace?
