Istanbul - A withdrawal of American ground forces in Syria will give Turkey freer rein to target Washington’s Kurdish partners in the fight against extremists but analysts doubt Ankara’s capacity to “eradicate” Daesh.

Turkish officials have said that President Recep Tayyip Erdogan heavily weighed in the decision by his US counterpart Donald Trump to pull all 2,000 American troops from Syria.

Trump’s shock order came after Erdogan convinced him that Turkey could eliminate the last remaining pockets of Daesh after the extremists suffered a series of military defeats.

“We have the strength to neutralise (Daesh) by ourselves,” Turkish Foreign Minister Mevlut Cavusoglu insisted on Tuesday.

But Erdogan’s main objective in Syria is actually to target the Kurdish People’s Protection Units (YPG) militia, which the US has trained to spearhead the fight against Daesh.

Turkey is vehemently opposed to a Kurdish entity on its border, fearing it will strengthen the separatist ambitions of the Kurdish minority inside the country, and says the YPG is a Syrian “terrorist” offshoot of the Kurdistan Workers’ Party (PKK).

The PKK, which has waged an insurgency against Turkey since 1984, is blacklisted as a terrorist organisation by Ankara and its Western allies.

Trump said on Sunday after a telephone conversation with Erdogan that he counted on him to “eradicate” Daesh which he said was now “largely defeated”.

Turkey has repeatedly called on the US to stop training and providing armed weapons to the YPG in the fight against Daesh, claiming that Turkish military forces would be more effective in eliminating the extremist threat.

“Erdogan is a victim of his own success in selling Trump on the idea that Turkey is ready to assume control over the counter-Daesh mission in Syria indefinitely,” Nicholas Heras, an analyst at the Centre for a New American Security, said.

“Turkey does not currently have a Syrian rebel force that is large enough, experienced enough, or legitimate enough to hold eastern Syria, and it would take many months, even with US support, for Turkey to amass such a force,” he added.

The last pockets of Daesh are in fact in eastern and central Syria, hundreds of kilometres away from the northern areas of the country which the Turkish military and Syrian rebels are accustomed to and where they led two offensives in 2016 and 2018.

“Daesh is close to Al Bu Kamal, more than 400km from Turkey, impossible for Turkey to go so far. The Syrian army and Iraqi Shiite militias will handle it after the US withdrawal,” said Syria expert Fabrice Balanche.

“Turkey is not even able to eliminate Hayat Tahrir Al Sham (HTS), ie. Al Qaida, from its border in Idlib, I cannot see how it can eliminate Daesh with the help of Arab militia,” he said.

Idlib is Syria’s last major rebel stronghold in the country’s north.

‘Real problem: logistics’

According to Balanche, Turkey could at most “prevent” an Daesh resurgence by closing its border with Syria to the extremists and carrying out targeted operations like in the Al Bab region of northern Syria in 2016.

Between August 2016 and March 2017, Turkish troops supported Syrian opposition fighters capture territory from Daesh in northern Syria.

Sinan Ulgen, chairman of the Istanbul-based Centre for Economics and Foreign Policy Studies, said that the distance between the last Daesh pockets and the Turkish border posed a “real problem” of logistics.

“So it is not clear how Turkey would orchestrate a military campaign at such long distances from its border in hostile territory,” he told AFP.

Lina Khatib, director of the Middle East and North Africa Programme at London-based Chatham House, said Erdogan gave assurances to Trump about his ability to eradicate Daesh without having a “plan” for doing so.

She said that Turkey’s real aim was to “use this opportunity (US withdrawal) to crack down on the YPG”.

“Eradicating Daesh can only happen through a comprehensive strategy that even the current international anti-Daesh coalition - which is limited to military action without adequate attention to the needed socioeconomic and political aspects of fighting Daesh - does not possess,” she added.

If Turkey were to fight Daesh alone and then left the battles to Syrian Arab proxies, “militarily weaker” than the extremists, it would not be very effective, Khatib said.

“This would also make Turkey vulnerable to revenge attacks by Daesh.”

Turkey was hit by a series of terror attacks blamed on Daesh in recent years including the last in January 2017 when a gunman killed 39 people in an Istanbul nightclub.
