ARKADELPHIA, Arkansas -- A recent New York Times carried the story that Japan will send 600 ground troops to southeastern Iraq. I read this news with sadness as I prepared to lead a discussion in my upper level class in 20th-century U.S. history on the dropping of the atomic bombs on Hiroshima and Nagasaki. Japan's role as voice for peace and nuclear disarmament is at stake.

The New York Times account rightly stressed that the meaning of Japan's pacifist Constitution is also at stake. Does anyone believe that the so-called Self-Defense Forces are on anything other than a military mission and acting as a combat army when they carry antitank weapons and drive armored vehicles into a war zone?

The subject of the dropping of the bomb is a highly personal one for me. I was born on Aug. 9, 1945, the day the United States dropped an atomic bomb on Nagasaki. I developed an understanding as I grew up of the great wrong committed by my government, and traveled to Hiroshima to visit the Peace Museum when I was a Fulbright lecturer five years ago at Tohoku University.
