[Machine Translation] After Japan's defeat in World War II, Article IX of its Constitution prohibited its military from engaging in overseas activities. Meanwhile, as Japan achieved a dramatic economic recovery and became one of the world's leading economic powers, there was a debate about the need for Japan to contribute not only economic aid but also human resources to the international community. What can Japan's Self-Defense Forces do, and what can they not do, in response to the tense international situation? The SDF's overseas deployment has been a turning point for Japan, from the Persian Gulf after the Gulf Crisis, the Iraq War, South Sudan, and Somalia to the war in Ukraine. This is a must-read book that covers the whole picture of Japan's overseas deployment of the Self-Defense Forces and the path that Japan should take.
