再軍備する日本 Japan Rearmed: The Politics of Military Power
Japan’s military is being tested not only by China, however. Other neighbors challenge Japan’s defenses. In the north, Russia continues to assert its military presence in and around Japanese air and waters.3 North Korea’s growing missile arsenal has raised serious questions about Japan’s ability to cope with a ballistic missile attack. In the face of these threats, the U.S. president has restated the U.S. commitment to Japan’s defenses several times. President Obama announced on a visit to Tokyo in 2014 that Article Five protections in the U.S.-Japan security treaty would extend to the Senkakus if force were used against Japan. When President Donald Trump met with Prime Minister Abe in Washington in February 2017, he restated this policy. Days later, when North Korea tested its missiles in the direction of Japanese territory, President Trump stood beside Prime Minister Abe at Mar-a-Lago to provide assurances that the United States would be “behind Japan, 100%” in dealing with Pyongyang’s threat. Part reassurance to the Japanese people, and part deterrence against China and North Korea, these declarations of American intentions reflect a growing worry about military activity around Japan.
