Japan's Self-Defense Forces, which came into existence 50 years ago, was described at the time as "armed forces with no war potential." Although that remains essentially true, the SDF is no longer a "passive" organization devoted only to national defense. As this year's defense report, issued earlier this month, points out, it is developing into a "functional" organization capable of performing a wider range of duties at home and abroad.
The annual report gives three reasons for improving or updating the SDF's functions. First, Japan faces a host of new security threats, such as weapons of mass destruction, ballistic missiles and terrorist attacks.
Second, the SDF's international role has increased. The aim is to cooperate in international efforts for peace and stability, such as U.N. peacekeeping operations, counterterrorism campaigns, and humanitarian and reconstruction activities.
