Who will dominate the post-Islamic State landscape in Iraq and Syria?
On the surface, the wars in Syria and Iraq are continuing at full intensity.† The fight between Iraqi government forces and the Islamic State in western Mosul is proving a slow, hard slog.† This week, government forces captured the police directorate and the courts complex in the city, moving toward the denser warren of the old city.† The jihadis are fighting for every inch of ground.† Further west, the US-supported Syrian Democratic Forces succeeded in cutting the last road from the IS capital of Raqqa to its stronghold in Deir al-Zur.
In the fight between the Assad regime and the Sunni Arab rebellion against it, a rebel attempt at a counter-attack in the city of Deraa has led to renewed bloodshed.† The regime is continuing its attacks on rebel-held Eastern Ghouta east of Damascus, despite a new Russian-brokered ceasefire.
But while the tactical contests are continuing, the general direction of events in both the war against IS and the fight between Assad and the rebels is now clear.
The Islamic State is on its way to ceasing to exist as an entity controlling significant territory.† This process is set to continue many months.† But IS, having lost tens of thousands of fighters and with the flow of new recruits drying up, facing enemies with complete control of the skies and vast superiority in numbers and equipment, has no means of reversing the trend.
In Assadís war further west, meanwhile, the rebellion is in retreat and its eventual eclipse seems a near certainty.† The regime, with its Iranian, Russian and Hizballah allies, is currently seeking to reduce and destroy isolated rebel held enclaves in the midst of regime-held territory in western Syria.† Hence the attacks on† eastern Ghouta, and on Waíer in the Homs area.† Once this is done, the pro-regime forces may well turn their attention to south west Syria, and eventually also to rebel-held Idleb province in the north.
The regime is also now engaging in the war against Islamic State.† Government forces† reached the Euphrates River this week, after sweeping through IS-held territory in the east Aleppo countryside.
As the direction of events becomes clear, so the possibility emerges of the Iran-led alliance achieving an overall victory in the Syria and Iraq wars.
Such a victory would on the face of it constitute an achievement for Assad.† But the Syrian dictatorís own forces are entirely dependent for advances on the Iranian Revolutionary Guards, Hizballah, Iraqi Shia militia forces and paramilitary formations created by the Iranians to address the regimeís manpower shortages over the last five years. That is, the real power behind such a victory would be Iran-arranged forces on the ground. These, in turn, are only capable of moving forward in cooperation with Russian air power, as events in Aleppo and the north west have shown.
Such an outcome is still distant, and is by no means certain.† But it is no longer an impossibility, and Israeli and US planners will be noting its feasibility, and seeking ways to prevent it or reduce its impact.
What would such a victory look like?
It would include the following elements: firstly, the Assad regime would succeed in terminating or severely reducing the remaining areas held by the Sunni Arab rebels and Islamists in the western part of the country.† Secondly, following the destruction of IS-held areas in eastern Syria, regime forces supported by Russian air power would succeed in heading eastwards, challenging or co-opting Kurdish and remaining rebel forces in the area, and reaching the Syrian-Iraqi border.
Thirdly, following the reduction or destruction of IS in Ninawah Province, the Iraqi Shia militias organized in the framework of the Popular Mobilization Units (PMU) would remain under arms, becoming a permanent feature of the Iraqi political and military landscape.
The Iraqi parliament in late November passed a law making the PMU a permanent part of the Iraqi security forces.† The 100,000 fighters of the PMU do not consist solely of pro-Iranian elements.† But the main militias and de facto command structures are in the hands of pro-Iranian forces. Most significantly, the Badr Corps of Hadi al-Ameri and the Ktaeb Hizballah group of Abu Mahdi Al-Muhandis are directly linked to Iranís Revolutionary Guards.
The militias are now located west of Mosul city, close to the town of Tel Afar.† If regime forces push eastwards, they will link at the border with their comrades of the PMU, creating a massive contiguous area of de facto Iran-controlled territory all the way from deep inside Iraq across Syria and into Lebanon.
That is what victory for the Iran-allied side in the wars in Syria and Iraq would look like.† How might it be prevented?
Advances for the Iranian side are only possible with the support of Russian air power.† And Russian goals in Syria (Iraq is less significant for Moscow) do not necessarily dovetail with Teheranís.† Iran wants total victory, the reunification of Syria under Assadís nominal control, and the emergence of the Iran-led Shia militias as the key power-holders in Iraq.
Moscow had and has far more limited goals.† The Russians in Syria wanted to prevent Assadís defeat, secure their naval assets on the Mediterranean and make themselves the main broker in the subsequent frozen or semi frozen conflict.
There is a large gap between these two agendas, and working on and widening it should be foremost in the minds of both western and Israeli policymakers.
The Russians need to understand that while their own perceived vital interests in Syria can be accomodated, the far more ambitious Iranian agenda in the area crosses western and Israeli red lines, and therefore will not be allowed to achieve its goals.† Without the Russians, western and Israeli efforts to contain and turn back the Iranians can proceed apace.
This can be achieved through a combination of diplomatic efforts and facts on the ground. Regarding the former, Prime Minister Benjamin Netanyahu in his visit to Russia will presumably be making clear to Russian President Vladimir Putin that† Israelís security red lines regarding Iranian and Hizballah creation of a new conflict line east of Quneitra Crossing, and regarding the need to prevent permanent Iranian bases in western Syria are serious, will be pursued, and can be achieved with no threat to Russian vital interests.
Regarding the latter, as of now the key force in Syria fighting Islamic State is the US-aligned SDF.† The latest reports indicate that elements of the US 75th Ranger regiment, and of the 11th Marine Expeditionary Unit are deploying in eastern Syria, to support the fight against IS in this area.
Ownership by the US and its allies of eastern Syria in the post IS-period is the best way to prevent the possibility of the realization of Iranís aims, while presenting Russia with a fait accompli.† The indications are that the US Administration is thinking in these terms. If so, Iranian victory emerging from the ruins of Syria and Iraq can be prevented.
The post-IS landscape in Iraq and Syria is emerging.† The contest for primacy within it is set to begin.
