In this article, In Hiroshima’s Shadow Noam Chomsky reminds us that August 6, the anniversary of Hiroshima, should be a day of somber reflection, not only on the terrible events of that day in 1945, but also on what they revealed: that humans, in their dedicated quest to extend their capacities for destruction, had finally found a way to approach the ultimate limit.
He also reminds us how at significant points in history since then leaders have acted with a clear understanding that they are increasing the risk that such an atrocity could be initiated again.
For example, historian Arthur M. Schlesinger Jr, refers to the Cuban missile crisis as an event initiated with a clear understanding of the risks of starting a nuclear war
Disaster was perilously close in 1962, and there has been no shortage of dangerous moments since. In 1973, in the last days of the Arab-Israeli war, Henry Kissinger called a high-level nuclear alert. India and Pakistan have come close to nuclear war. There have been innumerable cases when human intervention aborted nuclear attack only moments before launch after false reports by automated systems. There is much to think about on August 6.
This is a good article about the failure of world leaders to grasp the opportunity to move to a less nuclear armed state of global affairs.
