Last week in this column, I suggested that Caroline Kennedy, the American ambassador to Japan, would be well advised to get the ball rolling on U.S. apologies for past misdeeds.

The anniversary of the Tokyo firebombing provides an opportunity to do so.

On the night of March 9-10, 1945, U.S. warplanes dropped incendiary bombs on eastern Tokyo, incinerating an estimated 100,000 civilians, injuring a million more and leaving a million homeless.
