The most comprehensive pro-and-con discussion of Israel's dilemma - does Israel attack Iran's nuclear installations or wait? - can be found in The Times of Israel article, "The most fateful decision of all."

Intelligence Committee Chair Describes Explosive Confrontation Between Israel Prime Minister Netanyahu and American Ambassador
Rep. Mike Rogers, the Michigan Republican who chairs the House
Intelligence Committee, says that his much-discussed meeting with
Israeli Prime Minister Benjamin Netanyahu in Jerusalem late last month
did, in fact, devolve into an sharp confrontation between Netanyahu and
the American ambassador to Israel, the former National Security Council
official (and former Obama campaign Jewish liaison), Dan Shapiro.
Rogers
told a Michigan radio interviewer earlier this week that he had not
previously witnessed such a high-level confrontation, and he described
Israeli leaders as being at "wits' end" over what they see as President
Obama's unwillingness to provide them with his "red lines" in the effort
to stop Iran's nuclear program. He also said that neither the Israelis
nor the Iranians believe that Obama would use force to stop the nuclear
program. (UPDATE: Rogers said as well he believes the Israelis will "probably" bomb Iran if they don't get clearer red lines from the U.S.) [more. . .]
