Turkey, EU migrant pact may falter

The foundations of Turkey’s agreement with the European Union to curb the flow of migrants into Greece are looking shaky.

With Turkey battling the Islamic State group as well as Kurdish militants both at home and in neighboring Syria, President Recep Tayyip Erdogan insists he won’t scale back the anti-terrorism legislation that European leaders say undermines democratic standards.

Even if he did, the EU may no longer be willing to make good on a promise to award visa-free travel to Turkey in return, according to Ian Lesser, senior director for foreign policy at the German Marshall Fund of the United States.

Mr. Erdogan’s response to a failed coup in July, worries in Europe about Mideast terrorism, and EU jitters over immigration after the Brexit vote in June have altered the political calculus since European leaders sealed their pact with Turkey in March.
