Prime Minister Binyamin Netanyahu’s surprise unity government deal with Kadima leader Shaul Mofaz has reasonably triggered mass speculation regarding the premier’s ulterior motives.The first question is whether or not this move was somehow motivated by Netanyahu’s plans for contending with Iran’s nuclear weapons program.It is hard to see how the formation of the unity government will impact Netanyahu’s policy options on that score. If the elections had been carried out in September, as we thought, Netanyahu would certainly have been reelected. US President Barack Obama, concerned about his foreign policy bona fides and the Jewish vote on the eve of his reelection bid, would have been unable to undermine Netanyahu on Iran or just about anything else. So from Netanyahu’s perspective, a September election date immunized him from White House pressure.True, Mofaz has been parroting former Mossad chief Meir Dagan’s attacks on Netanyahu, but those criticisms have had no impact on Netanyahu’s options or public standing. This is particularly true because Dagan and his associates actually share Netanyahu’s assessment of the Iranian threat. They all say that if Iran acquires nuclear weapons it will constitute an existential threat to Israel.They all say that if all other options fail, that Israel will be forced to attack Iran’s nuclear installations militarily. They just don’t want Netanyahu to be the man dealing with the issue because they hate him personally.Dagan and his colleagues, Mofaz, and Obama all know that the Israeli public will rally around Netanyahu in the event he orders an attack. So widening the coalition would only impact his decision on Iran at the margins, if at all. It is true that from the perspective of political optics, it is better for Netanyahu to order an attack on Iran with a massive coalition standing behind him.Some on the right have voiced concerns that Netanyahu wants this coalition so he can reinstate negotiations with the Palestinians and withdraw from Judea and Samaria. Maybe. But it’s hard to see why Netanyahu would want to go full speed ahead on that issue. What would he stand to gain? Moreover, the Palestinians are the ones who ended the talks, not Netanyahu. And with Islamists rising to power throughout the Arab world and in Egypt particularly, Fatah head Mahmoud Abbas has no incentive to return to negotiations.ASIDE FROM that, it is possible that Netanyahu will use the cover he gets from Kadima to destroy homes in Beit El along the lines that the Supreme Court has ordered by July. But he probably would have done it anyway – or not. It all depends on what he thinks he can get away with. If he decides not to destroy them, it will be easier for him to stand up the Supreme Court, whose decision doesn’t pass the laugh test, with a coalition of 94 than with a coalition of 66. And it will be easier for him to bow to the decision of the Supreme Court with a coalition of 94 than a coalition of 66.Here it is important to note that to a large extent, Netanyahu has built his present power on his refusal to commit seriously to any binding position on the Palestinians. It is hard to see how he stands to gain from following in former prime minister Ariel Sharon’s footsteps and betraying his political camp and ideology completely.When taken on its merits, the unity deal is an example of a situation in which Netanyahu was presented with an offer he’d be an idiot to refuse. In return for essentially nothing, he built himself the strongest and largest coalition Israel has ever seen. He gave Mofaz nothing but breathing space for a year.Mofaz didn’t even receive a governing portfolio. And in exchange for his parsimonious offer, Mofaz gave Netanyahu unprecedented power and political stability for more than a year.Mofaz’s reason for acting as he did is clear. Kadima was set to lose half its seats in the Knesset in the next election.It may still lose half its seats in the next election. It may split apart. A million things can happen. But Mofaz probably figured that whereas if the elections were held in September he’d be blamed for the loss, by October 2013, he will have figured out someone else to blame for the defeat of his party.Finally, there is an economic aspect to this decision. By bringing Kadima into his coalition, Netanyahu effectively ensured that his free market economic policies will be maintained and the socialist voices in Israeli politics will be marginalized for the next year or so.With France going socialist, Israel’s Left, led by Labor Party leader and Marxist Shelly Yacimovich would have had more resonance in the public for its statist, deficit spending economic platform.Now Netanyahu got another year during which the public will see what those policies are doing to Europe and so make his economic arguments for him.All in all this is a great day for Netanyahu. It is to be hoped that he won’t use his new strength to destroy his political party as Sharon did before him. No previous action on Netanyahu’s part lends to that conclusion.But certainly Likud members who are in politics to represent and advance their values and not just to gain power for power’s sake need to think carefully about their strengths and weaknesses.They need to base their actions over the next year on a strategy that maximizes the former and minimizes the latter understanding all the time that they are dealing with an incredibly powerful party leader.
