The United States is reportedly considering withdrawing all its troops from Syria, according to a Wall Street Journal report published on Thursday. Citing unnamed U.S. officials, the report said the Syrian government has launched a major offensive against the Syrian Democratic Forces (SDF) in the country’s north. If the SDF collapses, officials indicated that there would be no further need for U.S. troops to remain in Syria. Currently, between 800 and 1,000 American soldiers are deployed there, and ongoing clashes between the SDF and Syrian forces have increased risks for U.S. personnel.

The offensive is part of Syrian President Ahmed al-Sharar’s effort to disarm militias formed during the 14-year civil war and integrate their fighters into the national army. Officials also noted that cooperation with the Syrian military would be problematic, as some of its members are sympathetic to jihadists and have been accused of atrocities against Kurdish and Druze minorities.

The SDF, once a key force against Islamic State militants, is viewed by both Ankara and Washington as a terrorist organization linked to the PKK, according to the report.
