Japan's decision to send Self-Defense Forces troops to Iraq, coupled with the decision to introduce a missile defense system, marks a major turning point for the nation's defense and security policy. Never in its 50-year history has the SDF been mobilized for noncombat duties in a foreign country in a de facto state of war.

In 1996, China conducted military exercises in waters near Taiwan. These events heightened the sense of crisis among the Japanese people.
