Israel, Hezbollah and Iran: Preventing Another War in Syria

The Syrian war has entered a new stage with the regime of Bashar al-Assad gaining the upper hand. Israel, no longer content to remain a bystander as Damascus’s position improves, is now jockeying to reverse the deterioration of its strategic posture. In this endeavor it has formidable obstacles to overcome: the regime is more dependent than ever on Iran, which Israel regards as its most implacable state foe; other enemies, particularly Hezbollah and Iran-backed Shiite militias, are entrenched in Syria with Russia’s blessing; and the U.S., notwithstanding the Trump administration’s strident rhetoric, has done little to reverse Iran’s gains. Yet Israel’s hand is not so weak. Russia has given it room to act against Iran-linked military interests and appears to be more interested in balancing contending fighting coalitions than returning every last piece of territory to the Assad regime’s control. But if Russia wishes to eventually withdraw or draw down its forces, it will need to broker rules of the game. Russia has indicated scant interest in doing so, but if it does not, hostilities between Israel and Iran may threaten its accomplishments, particularly regime stability.

Israel’s initial concern was Syria’s south west, where it is determined to prevent Hezbollah or Shiite militias from approaching the 1974 armistice line and setting up offensive infrastructure in its vicinity. Their doing so, as Israel sees it, could mean a new front against it and put Hezbollah in a position to launch attacks from an area in which its Lebanese civilian constituencies would not have to suffer Israeli counter-attacks. The Israeli army, its planners fear, would be left to exact costs in Lebanon, Damascus or Tehran, with the risk of provoking a regional war.

For the moment, a “de-escalation zone” sponsored by Jordan, Russia and the U.S. is keeping Hezbollah and other militias at a distance from the armistice line. But there are signs this arrangement might not hold. Regime forces in January 2018 seized territory from a jihadist group in the zone, enabling allied militias to creep closer to the Israeli-occupied Golan. Isolated Hezbollah forces already are present in the zone and probing its edges. This deterioration could be slowed by bolstering the de-escalation agreement, an element of the 1974 separation of forces agreement between Israel and Syria. But the moment of truth will arrive when the war winds down in other theaters: will the regime make good on its vow to retake the whole country, including the south west? Israeli Prime Minister Benjamin Netanyahu seems to assume that if the regime pursues this goal in earnest, inevitably the assistance of foreign forces will follow.

More broadly, Israel wants to prevent its rivals from consolidating a permanent military presence anywhere in Syria, which, it fears, would strengthen their hand in future wars as well as their influence today in Lebanon, Jordan and the Palestinian arena. Iran is of particular concern: Israel’s red lines seek to block it from establishing an airport, naval port, military base, permanent presence of militias or precision weapon production facilities for Hezbollah. Israel has already demonstrated its resolve to disrupt the construction of this sort of major military infrastructure. Russia by and large seems content to let this pattern continue and neither Iran nor Syria can stop it.

Yet Israel’s strikes against militiamen will prove riskier to pursue and easier to thwart, for instance by integrating the fighters into the Syrian army or simply having them don its uniforms. Israeli officials are also concerned at the prospect of a territorial corridor controlled by Iran-linked forces stretching via Iraq into Syria and Lebanon, which arguably could facilitate the movement of fighters and materiel. This development, too, will be harder for Israel to stop, particularly in Syria’s east, since its intelligence and military capacities decrease with distance from the Golan.

Only Moscow is in a position to mediate a bolstering of the de-escalation agreement. Unless it does, the rules of the Syrian game are likely to be worked out through attack and response, with risk of escalation. Attacks by Iran-backed groups over the armistice line dropped over the last couple of years, but Assad’s January 2018 seizure of adjacent territory may augur an increase. Israel too may attack, in the form of limited strikes to prevent Hezbollah from acquiring precision weapons facilities in Lebanon, which it has accused Iran of pursuing. Israel’s military establishment assesses it could do so without provoking an all-out confrontation. Perhaps, but Hezbollah has signaled that the consequences of such a strike are unpredictable. A broader war could be only a miscalculation away.

Regional changes make that miscalculation more likely. An increasingly assertive U.S.-Saudi strategy, with help from Israel, is taking shape to pressure Iran militarily, economically and diplomatically. These powers have adopted an activist posture to establish the deterrence vis-à-vis Iran that they feel was lost during the Barack Obama administration. Hezbollah and Iran of course have ways to reply. Neither Hezbollah nor Israel is a pawn of its allies and both have reasons, particularly the threat to civilian populations, to avoid a major escalation. But hostilities are unlikely to remain local.

In Syria’s south west, Russia appears to be the sole actor capable of mediating understandings to prevent an Iran-Israel escalation across the country. The best currently anticipated outcome would be a deal whereby Iran and its partners forego building major military infrastructure, including but not only in Syria’s south west, but retain significant influence in the country through other means. It is difficult to imagine a reversion to the pre-2011 situation, when the Syrian state, while allied with Iran, was not an arena for an open Iranian presence and military operations. For the foreseeable future, Iran will continue to be a pillar of the regime’s security. But it risks undermining its investment should it overplay its hand.

Everyone stands to lose from an intensification of the Syrian war, first and foremost the Syrian people. So too do Israel and Lebanon, since an altercation between them involving Hezbollah could ignite another war across their borders and beyond. As for Damascus and its backers, a massive campaign by Israel will do enormous damage to their achievements, perhaps even destabilizing the regime itself, which would sow discord between Russia and Israel. Gradually stabilizing Syria would be a wiser course, and the only viable one toward an eventual settlement.

  1. I am opposed to war but Israel’s hegemony must be confronted. Otherwise, it will continue to sow discord and conflicts in the Middle east for decades to come resulting in more destruction and dismemberment of the countries in the region.

  2. Got it. Israel wants a completely disarmed Syria and while Israel can fortify the Golan Heights (which could be used as a staging area for invasion circa Lebanon 1980), they don’t want to see opposing fortifications. Is that all?

    Syria is still bleeding bleeding from Al Qaeda aligned rebels, Iran, Iraq, Syria, and Lebanon are natural allies and want to be able to have ‘a corridor’ to pool their defensive capabilities. They have already lost tens of thousands of people but we have to worry about Israel’s anxiety about possible future scenarios as if Hezbollah could ever launch a serious ground invasion.

    The truth of the matter is that Israel likes being able to bomb their neighbors without fear of retaliation. The prospect that their neighbors might have a deterrent missile force to make that too costly and have have to treat their neighbors as peers, is a bitter pill for them to swallow. I get it, no one wants to give up a perceived advantage. Hey, we are the United States, we consider the ability to bomb people without retaliation our birthright. But this unreasonable expectation will condemn the region to unnecessary bloodshed. We should not indulge it.

  3. Israel, Israel, Israel. . .that little state smaller than New Jersey with less people, is out of it. The adults, Russia, Turkey & Iran will decide on the Syria deescalation zones while they (along with Syria of course) continue to dominate the conditions in the ground, killing rebels. That excepts eastern Syria for the moment, but that occupation of Arab Syrian land by Kurds and Americans will die on the vine eventually.
