I'm not saying Netanyahu or AIPAC or anyone else wants war. But, for whatever reason (I list some possible reasons below), they favor a negotiating stance toward Iran that is pretty much guaranteed to fail. Netanyahu says no deal should let Iran produce uranium enriched even to low levels, for civilian use, as permitted under the Nuclear Non-Proliferation Treaty--not even if the deal includes unprecedentedly strict monitoring to ensure compliance. And everyone I've talked to who knows much about Iran says one thing no Iranian regime can afford to do is surrender the "right to enrich" that most Iranians believe is theirs, and that the Iranian leadership has invested so much rhetorical capital in.

Any first-term president who hopes for re-election (that is, any first-term president) is mindful of lobbies, whether the sugar lobby, the Cuba lobby, or the Israel lobby. So any new president would likely have a harder time peacefully solving the Iran problem than a second-term President Obama. But for Romney this disadvantage is compounded by two factors.

First, assuming he sticks with something like his current foreign policy team, Romney will have some advisers who are "pro-Israel" in a particularly right-wing, hawkish sense of the term. Which is to say: they'll likely align with Netanyahu on the Iran issue. (This isn't the place for my sermon about how this right-wing brand of "pro-Israel" is often--including in this case--anti-Israel in the sense that it undermines Israel's long-term security.)

Second, a President Romney would be beholden to mega-donor Sheldon Adelson, who is "pro-Israel" in the unfortunate sense I've just described. According to the Associated Press, Adelson has already given $34 million to "Romney and organizations supporting Romney this election, making him the donor of donors for the GOP." And Adelson has said he could eventually provide as much as $100 million--an amount that, however outlandish it sounds, he might actually approach now that the race is so tight. But even if he stopped at $34 million, Adelson would be on a President Romney's very, very short list of "donors I least want to antagonize before 2016." To believe that donations of this mind-boggling magnitude don't significantly influence a president's policy positions is to believe that money plays no role in politics.

During the primary season, when Adelson was supporting Newt Gingrich, Ted Koppel asked Gingrich, "If you win, what does Adelson get out of it?" Gingrich replied, "Well, he knows I'm very pro-Israel. And that's the central value of his life." Nothing scandalous about that; donors have values, and politicians pay attention to them. For better or worse, that's life in America. The problem is Adelson's confused conception of how to serve Israel's interests.

Adelson enthusiastically echoed Gingrich's famous dismissal of Palestinians as an "invented" people, and he has long been hostile to a two-state solution, even though that could help relieve Israel's longstanding and corrosive sense of siege. He's compared supporting the Palestinian Authority to helping Israel commit suicide. His views on Israel are so extreme that when he criticizes AIPAC (which he's given much money to), he does so from the right.
