Splinter Cell: Chaos Theory

Japan's creation of an Information Self Defense Force is deemed a violation of international law and of their own Constitution and ignites rising tensions between Japan, China and North Korea.

Facing North Korean and Chinese blockades of shipping across the Korea Strait, Japan requests US assistance in accordance with American obligations under Article 9 of the Japanese Post War Constitution. Mounting evidence gathered by the I-SDF indicates that the devastation of the Japanese economy on the now infamous Black Gold Day may have been caused by intentional Information Warfare attacks.

As nations begin to mobilize and the United States activates the USS Clarence E Walsh, the world's premiere Electronic and Information Warfare platform and dispatches her to the region, Third Echelon gets wind of a small and seemingly unrelated incident that may end up having global repercussions.
