Will Erdogan Invade Syria?

A ground incursion into northern Syria could pose numerous longer-term threats to Turkey.

A ground incursion into northern Syria could pose numerous longer-term threats to Turkey.

Recent media reports suggest that Turkey could be preparing a military incursion inside Syria.

Despite the potential short-term political benefits for the AKP, Turkey’s ruling party, a ground incursion into northern Syria could pose numerous longer-term threats to Turkey itself.

The threats include renewed Kurdish separatism, economic retaliation by Russia and armed reprisals by the Assad regime, the PYD and ISIS.

Specifically, Turkish forces may be aiming to seize a 55-mile-long stretch of territory from Azaz in the west to Jarabulus in the east, thus establishing a 20-mile-deep cordon sanitaire against the violence next door and creating a staging ground for pro-Turkey Syrian rebels.

The Justice and Development (AKP) government received authorization from parliament last October to deploy troops in Syria or Iraq, if necessary.

On July 2, the opposition Nationalist Action Party (MHP) — which is in coalition talks with the AKP — signaled its support for such an operation.

Nevertheless, other Turkish domestic considerations bet against such an operation, with potential obstacles including a reluctant military, lack of public support and opposition from the Republican People’s Party (CHP) and Peoples’ Democratic Party (HDP).

These factors raise questions about what Ankara might gain and lose from taking action in Syria.

Block the PYD’s westward march

Until recently, the Syrian side of Turkey’s 510-mile border was controlled by a plethora of actors, including the pro-Kurdish Democratic Union Party (PYD), ISIS (“Islamic State”), Jaish al-Fatah (dominated by al Qaeda affiliate Jabhat al-Nusra), and moderate elements of the rebel Free Syrian Army.

The PYD is linked to the Kurdistan Workers Party (PKK), which Turkey fought for decades until entering peace talks with the group in 2012.

The PYD has controlled three isolated enclaves in Syria for some time: Afrin in the northwest, Kobane in the north-central region, and Jazeera in the northeast.

In May, with the help of U.S. airstrikes, the group seized a nearly 60-mile stretch of ISIS territory between the Jazeera and Kobane enclaves, effectively establishing a 250-mile-long PYD-controlled zone.

Ankara now fears that the group may decide to link all three of its enclaves by moving further west and capturing territory between Azaz and Jarabulus. This would be a momentous task.

While the PYD might be able to establish military control over the Azaz-Jarabulus belt with U.S. air support, it would have difficulty holding onto these Arab-majority areas, short of a major ethnic cleansing campaign.

Nevertheless, Ankara may try to preempt what it sees as a potential 385-mile-long PKK-run cordon to the south.

Lose the Turkish Kurds

Turkey’s Kurdish community is excited about the HDP’s success in the June 7 parliamentary elections. Running alongside various liberal factions, the party won an unprecedented 80 seats in the legislature, tied for the third-largest bloc.

The Kurds now believe that their demands for political and language rights cannot be ignored anymore. Turkish Kurds are also excited about recent developments in Iraq and Syria, where fellow Kurds have earned varying degrees of autonomy.

They have taken an especially deep interest in the fate of Syrian Kurds, a majority of whom live in the three enclaves right across the border. Personal, familial, geographic, and political connections run deepest between Turkish and Syrian Kurds.

The PKK and its sister PYD enjoy similar dominance among large sectors of the Kurdish community on both sides of the border. This explains the earthquake effect that the Kobane crisis had on Turkish politics beginning last year.

In September 2014, when the PYD-controlled enclave came under ISIS attack, Ankara initially refused to help, hoping to use the crisis as a bargaining tool to bring the PYD and PKK under its control.

This strategy backfired: the United States intervened with weapons and airstrikes, and Kobane survived to become a Kurdish symbol.

Ankara’s decision also shattered the previously strong Kurdish support for Recep Tayyip Erdogan‘s AKP. Many conservative Kurds who had backed the AKP in the past switched their votes to the HDP, helping the latter more than double its tally compared to the 2011 elections.

A Turkish military effort to block the PYD would only compound the Kobane effect. The AKP could lose all Kurdish support, or, worse yet, the Kurds could decide to break away completely from Ankara.

Turkish Kurds view the fate of the Syrian Kurds in the same way that Turks view their own ethnic brethren in northern Cyprus — and expect the government to offer a similar level of protection for them.

If Ankara moves to block the Kurds in Syria instead of helping them, it could rupture Kurdish political and emotional commitment to the Turkish state, with repercussions for domestic stability.

Establish an anti-Assad staging ground

In recent months, Turkey, Qatar and Saudi Arabia have pooled their resources to provide more weapons to opposition forces in northern Syria. This has allowed Jaish al-Fatah/Jabhat al-Nusra to take control of Idlib, the first provincial capital to be captured by this alliance.

A Turkish military zone in Syria — which could extend to the outskirts of Aleppo, Syria’s largest city before the war — would provide a staging ground for this alliance to threaten and perhaps even overrun Aleppo, furthering the AKP’s goal of ousting the Assad regime.

Resettle refugees back in Syria

Intervening in Syria could help Turkey alleviate its burgeoning refugee problem. The country hosts nearly two million Syrian refugees, the largest such population in the world. Many of them are poor people from the Syrian countryside, often traumatized by the war.

Their increasing presence in Turkish cities and camps has led to social and economic tensions that have spurred resentment against the AKP’s Syria policy.

To address this problem, Ankara could transfer some of the displaced persons into a military zone across the border — namely, the 300,000 or so currently residing in Turkish camps, as well as potential future refugees.

Incur the wrath of Assad, Russia, Iran and ISIS

A Turkish incursion to help the rebels would invite the wrath of the Assad regime, which is known to have connections to Marxist terrorist groups inside Turkey. Bashar al-Assad’s chief international sponsor (Moscow) and regional patron (Tehran) would also be upset by such a move.

Russia and Iran have historical connections to the PKK and could support the group in destabilizing any Turkish military zone inside Syria. Moscow could also push for anti-Turkish resolutions at the UN, though the United States might block such efforts.

Finally, Russia could use its energy card against Ankara — Turkey buys over half of its natural gas and oil from Russia and a cut in supplies would hurt its economy severely.

For its part, ISIS might acquiesce to a Turkish incursion at first. The group would rather lose territory to Ankara than to its archenemies, the PYD and the United States. ISIS fighters might even pull back from certain areas without putting up a significant fight against Turkish forces.

Yet a Turkish military zone would ultimately empower anti-ISIS rebel elements, so the group would inevitably begin harboring resentment toward Ankara. In the long term, Turkey would face a serious ISIS threat.

Give the AKP a lifeline

Erdogan could cast a speedy Turkish takeover of Syrian territory as a victory for his AKP.

This would help the party if Turkey were forced to undergo early elections.

According to Turkey’s constitution, a new government must be formed within 45 days after the speaker of parliament and deputy speakers are chosen following elections.

The new speaker was named on July 1 and the deputy speakers will be elected next week, at which point the clock will start ticking. The AKP has a plurality of votes in the legislature but is short of the majority needed to form a government.

Should its coalition negotiations with other parties fail to produce a government with a vote of confidence by mid-August, new elections will have to be held. In that scenario, a Turkish incursion in Syria would cost the AKP further Kurdish support at the ballot box.

At the same time, however, such a “victory operation” would bring in conservative voters from the MHP, with Erdogan hoping that this surge in support would help the AKP win an outright majority.

Destabilize Turkey in the long term

A military operation in Syria could raise several long-term security and political challenges for Ankara. In addition to the previously mentioned threats, Turkey would also eventually become an “occupier” in the eyes of the Syrian public, including the very forces it intended to boost.

In the end, it may have to choose between making a costly long-term commitment to defend a military zone between Jarabulus and Azaz or to withdraw from the area and thereby concede “defeat.”

Implications for U.S. policy

The U.S. posture on Turkish intervention would depend on the operation’s details, scope and impact. Washington is less likely to support a full-scale military incursion involving ground troops.

Turkey is a NATO ally — and such an operation could threaten to drag the United States into Syria’s war.

In contrast, a smaller operation — limited to sustained shelling deep inside Syrian territory to create a safe haven for rebel groups — would not be unwelcome in Washington, especially since it would cut ISIS’s supply lines and push the group out of certain areas.

And if Turkey can establish a modus operandi with the PYD rather than ending up in conflict with the group, that would be an extra sweetener for tacit U.S. support, including access to certain U.S. military assets.


A Turkish military effort to block the PYD would make AKP lose all Kurdish support.

The PYD will be unable to hold onto Arab-majority areas short of a major ethnic cleansing campaign.

Intervening in Syria could help Turkey alleviate its burgeoning refugee problem.

ISIS would rather lose territory to Ankara than to the PYD and the United States.
