I do not understand the caginess, this long after the events.

The left (academia) is heavily invested in the belief that America is evil. They prefer to downplay anything that suggests otherwise.

It is not just the USA that is trying to forget- just recently there was a spate of articles about how Japan is purging mentions of the Nanking affair from their history.

As for the left downplaying it because it makes us less evil, makes the Japanese less the aggressor, that has considerable merit, I think.
