‘Lunacy.” That’s how Danny Danon describes Prime Minister Binyamin Netanyahu’s decision to hand over 104 killers to the Palestinian Authority as a “goodwill gesture.”He’s hardly alone, as many observers (including myself) are outraged by this move. But Danon, 42, has a unique place in this debate because he (1) sits in the parliament as a member of Netanyahu’s Likud Party, (2) is chairman of Likud’s powerful central committee, and (3) serves as the country’s deputy defense minister. In American terms, his criticism resembles Gen.The writer is president of the Middle East Forum.Stanley McChrystal’s 2010 interview mocking Vice President Joe Biden. But McChrystal was gone within days, whereas Danon continues to gain influence and stature.Danon’s ability to denounce his own prime minister’s actions points to his not being a routine politician. Three qualities stand out: a devotion to principle, a mastery of tactics, and the ability to articulate a vision.Danon has remained true to the core principles of his party and his country.His righteous opposition when his party makes mistakes – such as the 2009 freeze on building residences for Jews in the West Bank, or accepting the two-state solution – shows a strength of character.As he points out, “It’s not easy being in a room of 30 people, alone saying no.”His rise through the country’s national camp institutions reveals tactical skill: serving as assistant to Uzi Landau, as head of the World Betar Organization, then head of the World Likud Organization, as organizer of street protests and challenger to the prime minister for the party’s leadership.These efforts culminated in his strong showing in his party’s electoral list (coming in No. 5) and the jaw-dropping 85 percent of the vote he won in elections to lead Likud’s central committee.With reason, The Forward newspaper calls him “a master of social and conventional media,” and the Times of Israel deems him “a major stumbling block toward Palestinian statehood.”Finally, the vision: Its fullest articulation is found in his 2012 book, Israel: The Will to Prevail (Palgrave), where he sketches an ambitious and contrarian view of his country’s foreign policy.Arguing that “history shows us Israel is often better off when she acts on her own behalf... even if that means contravening the wishes of US administrations,” he concludes that the Jewish state “fares best when she makes decisions based on her own best interests.”Jerusalem, he holds, should pursue its goals “with or without backing from her allies.” This argument, commonplace enough for most states, is audacious in the case of small, beleaguered Israel.Danon’s moment may have arrived.As Netanyahu appears to be making excessive and immoral concessions to the PA, Danon has emerged as a leading dissident ready to challenge his prime minister (remember “lunacy”).Should Netanyahu feel no longer welcome in his own party and leave it to found a new one (following exactly in Ariel Sharon’s 2005 footsteps), Danon will be a potential candidate to lead the Likud and win a subsequent election.One sign of his rise is the invective used against him. Justice Minister Tzipi Livni coined the term “Danonism” and demanded that Netanyahu reject it.Gideon Levy, an extreme-Left columnist for Haaretz, disdainfully but fearfully writes that “little Danny Danon will be big, the sugar of the Israeli right.... [He] will go far.”Viewed in historical perspective, since the taciturn but principled Yitzhak Shamir left the prime ministry in 1992, his six successors have variously engaged in political betrayal, ethical corruption and delusional egotism. Sharon (2001-06) abandoned his electoral mandate to the point that he had to flee his own party, even as his financial shenanigans had him in constant trouble with the law.Ehud Olmert (2006-09) had to resign due to a cloud of corruption charges.Focused on the Iranian threat, Netanyahu was doing well since 2009, but his recent offer of 104 murderers disturbingly contradicts the electoral platform of half a year ago.On a personal note, through the two decades since Shamir, I have constantly looked for someone with the character, energy, skills and vision to lead Israel. I have known Danon since 2009 and have concluded that he has the necessary qualities. I hope and expect he will stay true to his principles and rise to the point where he can end the recent desultory politics of the Jewish state and bring them in line with the country’s many remarkable achievements.Much hangs in the balance.
