State of War (novel)

State of War is a political thriller novel written by Tom Clancy and Martin Greenberg, published posthumously in 2003. Although billed under Clancy's name, the actual writing was primarily undertaken by Martin Greenberg following Clancy's detailed outline and notes. The novel continues Clancy's distinctive style of technothriller writing, incorporating detailed technical descriptions of weaponry and geopolitical situations.

The plot centers around a complex international crisis triggered by North Korea's aggressive actions, specifically a suspected test of a new, advanced missile. The United States, under the leadership of President Jack Ryan (a recurring character in Clancy's works), must navigate the volatile situation, deploying military assets and engaging in intense diplomatic negotiations to prevent a full-scale war. The narrative incorporates multiple perspectives, including those of government officials, military personnel, intelligence officers, and even individuals within North Korea, providing a broad view of the escalating conflict.

Key themes explored within the novel include nuclear proliferation, the dangers of rogue states, the complexities of international relations, and the ethical considerations involved in military intervention. State of War also delves into the internal workings of the U.S. government, highlighting the challenges faced by policymakers in high-pressure situations.
