Benny Gantz, chairman of the new Israel Resilience Party, got off to a fine start last week with a smooth speech. My esteemed Jerusalem Post columnist colleague Prof. Gil Troy enthused that it was an “oratorical grand slam” and a “testament to temperament” which “showed how to dream and build.”I’ll grant that Gantz has charmed the Israeli electorate with soaring Zionist rhetoric, and his rising poll numbers reflect this. His sunny deportment offers a counterpoint to Prime Minister Benjamin Netanyahu’s negative campaign messaging. And let’s face it, Netanyahu has been in office for a very long time, and some voter fatigue is setting in.But when evaluating Lt.- Gen. (res.) Gantz’s suitability to lead Israel, inevitably we must seek-out his defense and diplomatic worldview. This has been hard to discern, and purposefully so.There was, however, one roaring policy hint in his inaugural speech. Gantz said, “If it turns out that there is no way to reach peace (with the Palestinians) at this time, we will shape a new reality. Israel will not be deprived of its status as a strong, Jewish and democratic state.”“Shaping a new reality” is code for unilateral Israeli action in Judea and Samaria, withdrawals from the West Bank, and disengagement from settlements – without peace or any diplomatic concessions from the Palestinians.Gantz went further in an interview with Yediot Aharonot this week, when he praised the unilateral Gaza withdrawal and the destruction of Gush Katif towns, saying they were “carried out with a lot of political consideration,” “done legally,” and “handled well.”“We must take the lessons of the disengagement and implement them in other areas,” he added ominously.This is both frightening and clarifying. It suggests that Gantz would willingly repeat the mistakes of former prime minister Ariel Sharon, and that in Resilience Party parlance the self-referential term “centrist” in reality means “leftist.”Gantz’s spokesmen are trying mightily to wiggle out of his remarks, contending that the reference to “lessons” in his interview referred only to the importance of preventing a rift in the nation (really?,) and making sure that any future border decisions include strict security provisions (sure).But Gantz’s hints at unilateral Israeli withdrawal don’t come in a vacuum. They have a pedigree. For seven years, center-left generals and Barak- Olmert-era officials have been pumping plans for more unilateral Israeli withdrawals.Ehud Barak and Shaul Mofaz, both former defense ministers, have touted unilateral Israeli action. “We are on borrowed time,” Barak said in 2012 speech. “If it isn’t possible to reach a permanent agreement with the Palestinians, we must consider an interim arrangement or even a unilateral move.”Maj.-Gen. (res.) Amos Yadlin, at the Institute for National Security Studies (INSS), backed up Barak with an “academic study” that reached the conclusion that no agreement can be reached with the Palestinians, and therefore Israel “should go forward [with withdrawals] without depending on the Palestinians.”In 2013, Barak’s former bureau chief, Gilad Sher, tabled a report that also advocated unilateral Israeli withdrawal.He then launched an organization called “Blue White Future” to push a “compensation law” that would provide payment to tens of thousands of settlers for leaving their West Bank homes.IN 2015, the same plan for unilateral withdrawals and the starving of settlements outside settlement blocs, even in the absence of peace with the Palestinians, was the political platform that Gen. Yadlin used when he stood as Zionist Union candidate for defense minister.Last month, Yadlin & Co. launched another version of their grand withdrawal plan, with Israel unilaterally granting a contiguous Palestinian “entity” on approximately 65% of the West Bank.The INSS “new strategic framework” is nicely wrapped up as “professional, politically- neutral” research (sic) that took a year of intensive discussions to produce.Lo and behold, private citizen Benny Gantz took part in these consultations. And, surprise, surprise, the plan is couched in lofty language about “taking Zionist initiative” – as was Gantz’s speech.The problem is that unilateral Israeli withdrawals will neither enhance Israeli security nor improve Israel’s international position and moral standing. As the Lebanon and Gaza precedents proved, unilateral Israeli withdrawals only guarantee continuation of the conflict and even its escalation, not its de-escalation.Nor will unilateral moves provide Israel with diplomatic breathing room. Withdrawing from one part of the territories won’t convince anyone that Israel has a right to keep other parts.On the contrary, a partial Israeli pullout will intensify the illegitimacy of any remaining presence in the territories.Every Israeli retreat is taken as proof that the territories are all stolen property that must be returned to their rightful Palestinian owners.Unilateral withdrawals will bolster Palestinian maximalism, not engender Palestinian cooperation or moderation.Worst of all, unilateral withdrawals will unnecessarily and unjustifiably tear asunder the internal fabric of Israel.It’s indefensible to tie a deathknell tourniquet on Israeli towns in Judea and Samaria – if at all – without comprehensive and sustainable peace in the offing.Gantz’s Resilience Party partner, Lt. Gen. (ret.) Moshe “Bogie” Ya’alon, knows that Palestinian radicalism and the unpredictable nature of regional events make Palestinian statehood a very doubtful venture.He says that Israel must not jeopardize its existence by embarking on rash initiatives – neither unilateral withdrawals nor annexations – that would radically worsen its situation, just to please proponents of “forward progress” at any cost.Moreover, Ya’alon supports significant increases in Jewish settlement of Judea and Samaria. How does this square with Gantz’s views? Perhaps Ya’alon should explain to Gantz that “Zionist initiative” means reinforcing Israel’s hold on the greater-Jerusalem envelope and other key settlement zones, not unilateral withdrawals.And that long-term “conflict management” is preferable to wild diplomatic escapades like unilateral withdrawals.And that managing the conflict indefinitely is not a cowardly choice by hapless political and military leaders, but a rational choice – especially when the Iranian challenge looms larger than ever on Israel’s horizons.Judicious conflict management requires a steady hand at the helm of state, and self-confidence in the justice of Israel’s long-term interests in Judea and Samaria.Most of all, it requires patience. It’s sad to learn that Benny Gantz is leaning toward precipitance.The writer is vice president of the Jerusalem Institute for Strategy and Security, jiss.org.il.
