On the 64th anniversary of Hiroshima, columnists around the world say the time for disarmament is right now.

A Nation's Experience  Trust us, says an editorial in the Japan Times. "As the only nation to have experienced atom bomb attacks and the horrors of nuclear devastation, Japan can provide impetus to the efforts that would eventually lead to creation of a nuclear-free world. It should not miss the chance to work together with the U.S. toward this goal."

The U.N. Chief's Case  U.N. Secretary General Ban Ki-moon offers a five-point plan for a nuclear-free world. "This, then, is my plan to drop the bomb. Global security challenges are serious enough without the risks from nuclear weapons or their acquisition by additional states or non-state actors."

Peace, Not Vengeance  In the Japan Times, Eric Freed says the Japanese don't commemorate the anniversary of the atomic bomb with calls for vengeance. "The remembering is done to try and express a profound respect for human life and to try to express a desire that we as a human community do not ever again do what we have done."

A Nuclear-Free Middle East  Shlomo Ben-Ami says Israel should be honest about its nuclear capabilities so the world can have "a serious debate serious debate about the urgency of a nuclear-free zone in the Middle East."

Obama's Nuclear Promises  Anne Penketh says Clinton's trip to North Korea shows that Obama is serious about disarmament, especially when it comes to Iran. "Obama has reached out to his former antagonist in order to play to Mr. Clinton's strengths. And he may have taken another step along the road to nuclear disarmament. Believe me, the Iranians are watching."
