The US has struck the Syrian airbase used to launch a suspected sarin gas attack against Khan Sheikhun that killed more than 80 civilians. US President Donald Trump and Secretary of State Rex Tillerson cited the chemical attack as the reason for their country’s first direct involvement in Syria’s six-year war.
A Pentagon spokesman said Russia was informed ahead of the attack on the al-Shayrat airbase. According to the Associated Press, opposition group the Syrian Coalition, has welcomed the intervention. The rebel commander whose district was hit by the suspected chemical weapon attack has said he hopes the strike will be a “turning point” in the war.
But the long-running conflict has had many such apparently pivotal moments.
The fall of Aleppo
By the end of 2016, for instance, opposition forces in the Syrian city of Aleppo had been overwhelmingly defeated, raising doubts about their ability to endure the fight against the Assad regime. Especially as the latter receives active support from the Russian government and Shi’a militias.
The battle of Aleppo, much like the Battle of Stalingrad in the second world war, was characterised by close-quarters combat, massive displacement, great destruction and recurring air raids on civilian populations and infrastructure.
Scholars and researchers were largely divided after the Aleppo assault. Some viewed the outcome as the beginning of the end for the losing party – the Stalingrad moment of the Syrian war. Others recognised the importance of the events without considering them decisive.
And, like the US missile strike, the suspected chemical attack on April 5 was perceived as another watershed moment. But, on the ground, the question is how these critical moments will shape the immediate options of warring factions.
Recent military developments in Hama and Damascus might indicate the direction the war is taking, with the rebels trying to recover from the battle of Aleppo and launching new offensives.
Aftermath the fall
After their defeat in Aleppo, many opposition groups reconsidered their inter-factional alliances. In the Idlib governorate and the countryside around Aleppo, for instance, a number of factions merged with what used to be known as the Nusra Front, or Jabhat Fath el-Sham, to form the new Hay’at Tahrir al-Sham.
Tensions heightened between these two prominent opposition groups as a number of Ahrar al-Sham combatants defected to the recently formed Hay’at Tahrir al-Sham. The outcome so far has been a delicate balance of power between these two large groups, which represent the most powerful opposition forces in Idlib and its vicinity.
Together they govern the last opposition stronghold, and Assad’s ultimate victory in Syria depends on the divisions and tensions between them. If these groups are not able to unite when and if pro-Assad forces rally again, Idlib, which is the only area under comprehensive rebel control, might go the way of Aleppo. Its fall would leave the opposition controlling only small isolated patches of territory.
Idlib and beyond
Given that Ahrar al-Sham and Hay’at Tahrir al-Sham have maintained their cooperation thus far, Idlib promises to be a much bigger challenge for the Assad regime than landlocked Aleppo. A siege on Idlib is practically impossible as long as its border with Turkey stays under opposition control.
The weakest point for the opposition in Idlib is the main passage between the governorate and Turkey, the Bab al-Hawa Crossing. If pro-government forces were to capture this strategic spot in an all-out siege of Idlib, it could enable another battle of attrition.
To disrupt the regime’s momentum and prevent it from regrouping its forces, this time around Idlib, both Hay’at Tahrir al-Sham and Ahrar al-Sham have launched an offensive on the Hama front. Since March 21 2017, opposition forces have taken dozens of government-held villages, coming within a few kilometres of the city of Hama.
Though the southward expansion from Idlib has thus far not reached isolated territories in Homs, a city bombarded by the government in 2012, the territorial gains provide a number of advantages. The Hama offensive creates a buffer zone for Idlib, and mobilises and positions opposition forces in threatening strategic locations. This compels pro-regime forces to either engage on insufficiently fortified fronts or withdraw to other defensive positions.
In light of these conditions, opposition forces near southern Aleppo may also attempt an offensive on the town of Khanasir, cutting off the government’s supply route to its forces in Aleppo and forcing pro-regime troops to disperse in different directions.
From that perspective, the suspected chemical attack could be seen as an attempt by Assad to distract the opposition from its advance southwards.
The Hama offensive
The Hama offensive opens new possibilities for the opposition. But to succeed on this front government forces must be kept occupied elsewhere. So, while opposition forces were mobilising in Hama, other rebel factions such as Faylaq al-Sham reopened the Damascus front in the areas of Qabun and Jobar, less than six kilometres from the heart of Syria’s capital.
Opposition forces have not made any significant gains yet. But the proximity of these new clashes to Damascus is sufficient to keep the regime’s forces in the area occupied and committed.
Another condition favouring opposition forces is the current vacuum in Syria’s sparsely populated Badiya desert region, resulting from the ongoing battle for Raqqa.
As the Kurdish-led Syrian Democratic Forces gathered north in the past few weeks, Islamic State forfeited southern areas to reinforce its positions in Raqqa and Tabqa. Meanwhile, Ahrar al-Sham and Western-backed Free Syrian Army forces expanded in eastern Qalamoun and reinforced their presence on the Jordanian and Iraqi borders in the southwest.
Islamic State has antagonised all armed factions in Syria, but the geographic proximity of the Syrian Democratic Forces to Raqqa makes them the likely inheritors of its abandoned territories in the north.
If the Syrian Democratic Forces were to expand towards Raqqa, it might lead Islamic State to redirect its forces southward to find safe havens in the Syrian desert. This would create an undesired distraction for opposition forces that recently captured territories in the southeast.
While battles are raging in Damascus in the areas around the districts of Jobar and Qaboun, different factions in the north and south are rallying against Islamic State to capitalise on its defeats.
These developments show that, following the battle of Aleppo, whatever advantage the Assad regime enjoyed heading into the latest round of Geneva talks in February may not last. And the proactive foreign support that pushed the Assad regime forwards on the ground could dissipate in light of recent events.
The key to Assad’s future may well lie with the Russian reaction to the US move. As the country woke to the news of the overnight attack, the head of the defence and security committee of the Russian upper house of parliament said his country would call for an urgent meeting of the UN Security Council.
Meanwhile, on the ground, government forces and opposition groups continue to mobilise, and territorial control keeps shifting. The irregular methods of warfare employed by armed rebels reinforce their resilience, flexibility and longevity in a war now entering its sixth bloody year.
Opposition groups may also find further air support from Turkey to expand their presence in Islamic State territories. While opposition groups will not be able to oust the regime, the regime will not be able to eliminate the opposition either.
A shift of US foreign policy on Syria could have been the game-changer. But the US airstrike is more likely to reinforce the balance of power between the combating factions rather than lead to a turning point.
