The Pentagon is continuing to support Kurdish forces in Iraq and Syria, a government audit revealed this week, even as the fight against the Islamic State (IS) winds down and the United States faces growing pressure from allies and foes alike to back down.

The latest quarterly Lead Inspector General (IG) report for the US-led mission in Iraq and Syria confirms that the Donald Trump administration continues to supply weapons and equipment to the Kurdish People’s Protection Units (YPG), part of the Syrian Democratic Forces (SDF). The Defense Department considers the YPG to be the most capable in-country US partner for the mission, but NATO ally Turkey views YPG fighters as terrorists.

For the fiscal year that started Oct. 1, the Pentagon asked for $500 million to supply Syrian forces, including YPG-led units, with vehicles, mortars, anti-tank missiles and machine guns, up from $430 million requested in fiscal 2017. Deliveries began in May 2017, prompting the ire of Turkish President Recep Tayyip Erdogan.

The IG report indicates that US support has kept up, despite pledges from US officials to draw down support amid increasing friction with both the Turks and Bashar al-Assad’s regime. A large battle outside SDF headquarters this week led to the deaths of more than 100 pro-Assad fighters who fired dozens of tank rounds at the Deir ez-Zor province compound, prompting the US-backed force to respond in self-defense, according to the Pentagon.
