Nothing Against the United States

In an article detailing the amazing survival of an infant after the devasting blast at Hiroshima 60 years ago, the now-grown survior has what may seem to be an unusual stance:

"Shimizu, a visiting teacher in the Carrollton Public School District, holds nothing against the United States for the attack. To the contrary, he said it ended a war that could have cost millions of lives."

A lot of Americans have made this comment, but this is the first time I have read of a Japanese person agreeing, especially a person who was on the receiving end of the blast. He adds:

"'It is better that they dropped the bomb,' said Shimizu, 25, who lives less than two miles from where the bomb exploded. 'If American Army didn't drop the bomb, the war probably would have continued.' Instead of harboring anger and resentment, Shimizu said his people mark the occasion with calls for peace."

The anniversary of Hiroshim naturally raises the question of if and when a war is justified. Dr. Steve Cowan's article on this matter is succint and helpful. Question - Was the destruction of Hiroshima and Nagasaki justified?
