An official apology?
What is wrong with you? "I have read a lot of history before making this movie." I seriously doubt it. You made this thing on the notion that the Americans bombed Hiroshima unprovoked. Why don't you get the facts straight. Does Pearle Harbor mean anything to you? Hiroshima and Nagasaki were a wake-up call for Japan, that they pissed off a much stronger force than them, and had to deal with the consequences.
The Japanese drug the United States into World War II. They suffered as a result. We don't owe them anything... and think about all the aid America has given out to practically every civilization in existence over the years, INCLUDING Japan. They owe US, not vice versa.
