Today marks the 64th anniversary of the bombing of Hiroshima.

The residents of Hiroshima had no way of knowing what was happening that morning as their city was engulfed in flames. More than 260,000 people are now considered to be victims of the attack. Many died that morning, but most succumbed to radiation sickness in the days and weeks that followed.

Yet today, as Tadatoshi Akiba—the mayor of Hiroshima—addressed a crowd of some 50,000 people, he issued a message of hope.

We refer to ourselves, the great global majority, as the ‘Obamajority,’ and we call on the rest of the world to join forces with us to eliminate all nuclear weapons by 2020. Together, we can abolish nuclear weapons. Yes, we can.

Visit the United Nations’ website today and sign a petiton to abolish nuclear weapons.

The genie is already out of the bottle, but we still have one wish left.
