A senior Israeli official said [on February 2] that the missile-testing site near Tehran that was destroyed in a huge explosion three months ago was developing missiles with a range of 6,000 miles aimed at the United States. The assertion went far beyond what rocket experts have established about Iran's missile capabilities, and U.S. officials questioned its accuracy. The Israeli official, Moshe Yaalon, a deputy prime minister, said the explosion, at a Revolutionary Guard missile base, hit a system getting ready to produce a missile with a range of 10,000 kilometers. It was aimed at America, not at us." Yaalon was trying to make the point that the Iranian nuclear program is not a threat only to Israel but, as he put it, "a nightmare for the free world." He said it was a concern to Arab states as well as to the United States and Israel. U.S. officials said they believed Yaalon's assertions were at best premature and at worst badly exaggerated. The officials said Iran ... is nowhere close to achieving such a capability. They declined to say what kind of missile work was being done at the base where the explosion took place. Today, the maximum range of Iran's known ballistic missiles is roughly 1,200 miles, rocket experts say.
