The Associated Press has gotten a hold of a graph leaked by " officials from a country critical of Iran's atomic program to bolster their arguments that Iran's nuclear program must be halted before it produces a weapon."

Iranian scientists have run computer simulations for a nuclear weapon that would produce more than triple the explosive force of the World War II bomb that destroyed Hiroshima, according to a diagram obtained by The Associated Press.

The diagram was leaked by officials from a country critical of Iran's atomic program to bolster their arguments that Iran's nuclear program must be halted before it produces a weapon. The officials provided the diagram only on condition that they and their country not be named.

The International Atomic Energy Agency - the Vienna-based U.N. nuclear watchdog - reported last year that it had obtained diagrams indicating that Iran was calculating the "nuclear explosive yield" of potential weapons. A senior diplomat who is considered neutral on the issue confirmed that the graph obtained by the AP was indeed one of those cited by the IAEA in that report. He spoke only on condition of anonymity because he was not authorized to discuss the issue.

The IAEA report mentioning the diagrams last year did not give details of what they showed. But the diagram seen by the AP shows a bell curve - with variables of time in micro-seconds, and power and energy both in kilotons - the traditional measurement of the energy output, and hence the destructive power of nuclear weapons. The curve peaks at just above 50 kilotons at around 2 microseconds, reflecting the full force of the weapon being modeled.

The bomb that the United States dropped on Hiroshima in Japan during World War II, in comparison, had a force of about 15 kilotons. Modern nuclear weapons have yields hundreds of times higher than that.

The diagram has a caption in Farsi: "Changes in output and in energy released as a function of time through power pulse." The number "5'' is part of the title, suggesting it is part of a series.

If the world doesn't care by now, they are not likely to care when Iran is nuclear capable. Only collective action by the world community of the most draconian kind can stop them now. And since that's not likely to happen, and since Obama is not likely to lift a finger unless Iran tests a device, Israel is alone in deciding whether to use military force to stop them.
