The basic concept of power is the ability to influence others to get them to do what you want. There are three major ways to do that: one is to threaten them with sticks; the second is to pay them with carrots; the third is to attract them or co-opt them, so that they want what you want. If you can get others to be attracted to want what you want, it costs you much less in carrots and sticks.
When Nye was serving as assistant secretary of defense, he formed the Nye Initiative, a security strategy which advocated firmly holding U.S. troop levels in East Asia at 100,000. Later, he researched policies toward Japan in nonpartisan dialogue with people including former U.S. Deputy Secretary of State Richard Armitage, a Republican versed in Japan. The result was the Armitage Report handling policy toward Japan, produced in 2000 and 2007.
The 2000 report pointed out the necessity of lessening the burden of U.S. troops in Okinawa. The 2007 report urged the Japanese and U.S. governments to prepare a security environment centering on secure trilateral relations between Japan, the United States and China, and between Japan, the United States and India.
