Mark #HiroshimaDay and #NagasakiDay by refusing to forget. By organizing. By educating. By challenging the systems that justified & still justify mass death in the name of “security.” @worldbeyondwar
The United States justifies Hiroshima & Nagasaki with false talk of “ending the war.” But the bombings were strategic displays of power rooted in racism, imperialism, & militarism — and unrelated to ending the war. @worldbeyondwar
There are still 13,000+ nuclear weapons in the world. The same logic that dropped the bomb in 1945 keeps many of them on hair-trigger alert today. Hiroshima and Nagasaki are not history. They are a warning. @worldbeyondwar
The anniversaries of Hiroshima and Nagasaki are about demanding a future without nuclear weapons. Over 200,000 people died. That number could be exponentially higher today. Join us in remembering and resisting. @worldbeyondwar
Hibakusha—survivors of the atomic bombings—have long warned the world: nuclear weapons must be abolished. Their voices are warnings for our present. Let’s listen. Let’s act. Let’s choose demilitarization over devastation. @worldbeyondwar
Every year, August 6 and 9 remind us what nuclear weapons do. The threat hasn’t gone away. Thousands of warheads remain, many on hair-trigger alert. We don’t need more military spending. We need a #WorldBEYONDWar.

Nuclear-Free Zones Should Be Expanded

Note that U.S. military bases create an exception to these zones. The U.S. government has refused to tell the Australian government, which apparently prefers not to know anyway, whether nuclear weapons are or ever will be at U.S. bases in Australia.

Note also that the practice of openly keeping nuclear weapons in other countries is growing quickly, with the U.S. maintaining nuclear bombs in Turkey, Germany, Netherlands, Italy, Belgium, and the UK; Russia putting nuclear weapons into Belarus; and France and the UK talking about putting their nuclear weapons into other countries — all arguably in violation of the treaty on nonproliferation, which in any case is blatantly violated by the failure to get rid of the nuclear weapons . . . and all other weapons!
