The revisionist essay by the former chief of the Air Self-Defense Force that has caused a controversy over Japan's wartime role will not affect the country's security alliance with the United States, the commander of U.S. Forces in Japan said Tuesday in Tokyo.

The essay by Gen. Toshio Tamogami has caused a stir both at home and abroad, as it defends Japan's military aggression in the 1930s and '40s and condemns the U.S.-led postwar military tribunal that convicted many Japanese leaders of war crimes.

However, Lt. Gen. Edward A. Rice Jr. was keen to stress that ties between Tokyo and Washington remain strong.
