I think Mr. Obama should pay his respects to the Japanese.  In the Hiroshima Memorial Museum the Japanese acknowledge that they were at war and that bad things happen when a country is at war.  "Respect".......to look backward (and take responsibility for one's actions).  Taking responsibility helps to rebridge in relationships between people and between countries.  It is said that our efforts saved lives.  In the museum one learns that the bomb contained 35 kilograms of enriched uranium yet only 3/4 kilogram detonated.  Had it actually exploded as designed and killed 10,000,000 people could anyone really argue that it saved lives?
