The government has opted to extend by one year the Maritime Self-Defense Force mission to supply fuel in the Indian Ocean to ships of the U.S. Navy and allied nations engaged in antiterrorist activities related to security in Afghanistan. A law specifying a duration of two years -- enacted after the Sept. 11, 2001, terrorist attacks in the United States -- has enabled the MSDF mission so far. That law will expire Nov. 1. The legislation raised a constitutional question, and should not be extended offhandedly.

International cooperation is important for thwarting terrorism. Afghanistan took a landmark step in its march toward peace and democracy by holding elections Sept. 18 for the National Assembly and Provincial Councils, the first such elections under its new Constitution. The fact that the elections occurred with relatively little confusion was a sign of progress that strengthens the case for ending the MSDF's mission.

Regrettably, this issue was not publicly debated during the recent election campaign as Prime Minister Junichiro Koizumi chose to focus on one issue essentially -- the postal service privatization bills. The government is scheduled to submit a revision bill that would extend the MSDF mission by one year to the current special session of the Diet. Thorough discussion is demanded of legislators.
