Pressure from the Israelis to attack Iran?

Lenin from Lenin's Tomb blog gathers the evidence:

"An IDF spokesman said after the meeting that the security establishment assessment was grim. “Only a military strike by the U.S. and its allies will stop Iran attaining nuclear weapons,” said the spokesman."

and here:
"The Washington Post reports that despite fact U.S. intelligence sources believe that Iran needs another 10 years before having nuclear weapons, Israel believes critical breakthrough will happen within months, and is therefore pressuring the Americans"

and here:
William Polk: "After careful study of recent moves and statements by the Bush Administration, I have concluded that there is at least a 10% chance of an American attack on Iran before the November 7 Congressional elections and about a 90% chance before the administration’s end in 2008."
