From Revealed: srael plans nuclear strike on Iran by Uzi Mahnaimi, New York and Sarah Baxter Times of London 01/07/06:
Israel has drawn up secret plans to destroy Iran’s uranium enrichment facilities with tactical nuclear weapons.
Two Israeli air force squadrons are training to blow up an Iranian facility using low-yield nuclear “bunker-busters”, according to several Israeli military sources.
The attack would be the first with nuclear weapons since 1945, when the United States dropped atomic bombs on Hiroshima and Nagasaki. The Israeli weapons would each have a force equivalent to one-fifteenth of the Hiroshima bomb.
Under the plans, conventional laser-guided bombs would open “tunnels” into the targets. “Mini-nukes” would then immediately be fired into a plant at Natanz, exploding deep underground to reduce the risk of radioactive fallout.
“As soon as the green light is given, it will be one mission, one strike and the Iranian nuclear project will be demolished,” said one of the sources.
One of the American Iran hawks' arguments has been that we need to bomb Iran because Israel might if we don't and that would be bad. It's a daffy argument, but the Iran hawks are daffy people. Also influential, unfortunately.
