Regarding Masanobu Saito's May 10 letter, "Obama should not visit Hiroshima": I'm rather confused by his logic. We have a saying: "Seeing his believing." If world leaders should take all necessary steps to ban nuclear weapons to save Earth, not only U.S. President Barack Obama but also Russian President Dmitry Medvedev and other world leaders should visit Hiroshima and Nagasaki to witness the real horror of the atomic bombs with their own eyes.

Saito says he doesn't believe that Obama, as the leader of the only country that has used A-bombs in war, should visit Hiroshima and Nagasaki. Why not? And why shouldn't this "delicate" subject be political? As a holder of the Hiroshima A-bomb victim's health book, he knows the real effects of the A-bomb. He should show world leaders what he has suffered.

Nobody can change the fact that America was the first in human history to use A-bombs in war. Obama doesn't have to apologize for what President Harry Truman did. But what Obama can and should do is lead the whole world toward the abolition of nuclear weapons to save not only humanity but all other living things on Earth. I believe a summit meeting on abolishing all nuclear weapons should be held in Hiroshima — under the dark shadow of unimaginable destruction.
