An interesting piece in Haaretz includes this tidbit:
Until the war in Iraq in 2003, CENTCOM refused any direct contact with Israelis. Dan Shomron, who visited MacDill as chief of staff in 1989, visited only SOCOM; he was not permitted to cross the fence to CENTCOM, lest the shocking presence of an Israeli officer become known to the Saudis and others. In recent years the Americans have been more daring, but it is still unusual for an Israeli to speak openly with a commander of CENTCOM Special Forces.
And later in the piece:
A general, one of Olson's subordinates, dared to walk the borderline of expressing an opinion about the U.S. elections: The strategic interests are basically unchanging, and the next administration must, after studying them, determine its policy accordingly. In other words - words the disciplined American officers would not utter - an operation in Iran is definitely being planned, no matter who is the next president. Iran's nuclear arming is supposed to be ready at the beginning of the decade, and there is the assistance to America's enemies in Iraq, in Afghanistan, in Lebanon and in Gaza. The outcome of the presidential election is more likely to affect the definition and timing of the mission than the decision itself.
