Operation Inherent Resolve (OIR) was a United States-led international military intervention against the Islamic State in Iraq, Syria, and Libya which was initiated in June 2014 in response to ISIL's rapid advance on the Iraqi capital of Baghdad. The US Air Force carried out several airstrikes against ISIL fighters, convoys, headquarters, bases, and other related targets in order to support ground offensive campaigns by Iraqi and Kurdish allies, turning the tide of ISIL's advances in 2014 and resulting in the lifting of the Siege of Kobani in early 2015. ISIL's defeat at Kobani led to ISIL's gradual retreat in the face of combined airstrikes and ground offensives. The United States conducted between 75% and 80% of the airstrikes involved in Operation Inherent Resolve, while the remaining 20% to 25% were carried out by its allies Britain, France, Turkey, Canada, the Netherlands, Denmark, Belgium, Saudi Arabia, the United Arab Emirates, and Jordan. By February 2016, over 30,000 ISIL fighters were reported to have been killed in allied airstrikes, and, by the time of the liberation of Mosul and the collapse of ISIL in Iraq in late 2017. the number of reported ISIL deaths at the hands of the Inherent Resolve coalition had risen to 80,000. By March 2019, the coalition had liberated up to 42,471 square miles of land and 7.7 million people from ISIL, and, by the end of August, the coalition had carried out 34,573 airstrikes. By the end of 2017, meanwhile, the American-backed Syrian Democratic Forces were reported to have killed 25,336 ISIL fighters on the ground, and, by the end of 2019, ISIL had lost all of its strongholds in Syria as well. The Islamic State's self-proclaimed caliph, Abu Bakr al-Baghdadi, was killed in the American JSOC Barisha raid on 26 October 2019, delivering a major blow to ISIL. However, ISIL continued to wage a war of attrition against the US-backed Iraqi government and Iraqi Kurdistan in Iraq and against the SDF in Syria, leading to the continued bombing of ISIL targets by the OIR coalition.
