During the Syrian Civil War, which began in 2011, the United States first supplied the rebels of the Free Syrian Army with non-lethal aid (including food rations and pickup trucks), but quickly began providing training, cash, and intelligence to selected Syrian rebel commanders to fund a proxy force against the sovereign state of Syria.
The United States began surveillance missions on ISIL positions in Syria in September 2014. On September 10, President Barack Obamagave a speech indicating his intent to “degrade and ultimately destroy”Islamic State of Iraq and the Levant (ISIL), saying, “I have made it clear that we will hunt down terrorists who threaten our country, wherever they are. That means I will not hesitate to take action against ISIL in Syria, as well as Iraq.”
On September 22, 2014, the United States, Bahrain, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates began to strike targets of the Islamic State of Iraq and the Levant (ISIL) inside Syria, as well as the Khorasan group in the Idlib Governorate to the west of Aleppo, and the al-Nusra Front around Ar-Raqqah, as part of the Military intervention against ISIL.
On November 2, 2015, in response to the intervention, representatives from Ahrar ash-Sham attended a meeting with the al-Nusra Front, the Khorasan Group, the ISIL, and Jund al-Aqsa, which sought to unite several hard-line groups against the US-led coalition and other moderate Syrian rebel groups. On November 6, a US airstrike struck Ahrar ash-Sham at its headquarters in Idlib. By 14 November 2014, it was revealed that the negotiations between al-Nusra, Jund al-Aqsa, ISIL and Ahrar ash-Sham had failed.
