"According to Netanyahu advisor Uzi Arad—a former Mossad official who was present at the 45-minute talk—Obama agreed with Netanyahu that "the paramount and most urgent issue is Iran," and that "a nuclear Iran is unacceptable not only to Israel but to the United States." Netanyahu "also made it clear to him that on the Iranian threat there is no dissension in Israel; this is a national attitude." In a telephone interview on Thursday, Arad told me that he believed that the Democratic candidate for president concurred with Netanyahu as well about the sequence of events that must occur: On Iran "the clocks and centrifuges are clicking and spinning, and not only is time of the essence but the order of things is as well. Should one fail to neutralize that Iranian threat now, it would undercut anything that would be achieved with the Palestinians, Syria or Lebanon.""
