What were the reasons behind the US-led coalition's intervention in the War in Syria?

The US-led coalition intervened in the Syrian War for a variety of reasons. One major factor was the Syrian government's use of chemical weapons against its own citizens in August 2013, which violated international law and prompted global outrage. The US and its allies believed that the Assad regime should be held accountable for this heinous crime and sought to prevent future use of such weapons. Additionally, the rise of the Islamic State (ISIS) in Syria and Iraq posed a significant threat to regional stability and security. The US-led coalition intervened to degrade and ultimately defeat ISIS, which was responsible for numerous terrorist attacks and human rights violations.

Another reason for the intervention was to support the Syrian opposition and push for a political solution to the conflict. The US and its allies provided military aid and training to various opposition groups in the hopes of weakening the Assad regime and forcing it to negotiate. However, this effort was complicated by the fact that some opposition groups were linked to extremist organizations like Al Qaeda.

The US-led coalition's intervention in the Syrian War was also influenced by geopolitical considerations. The conflict had drawn in various regional and global powers, including Russia, Iran, and Turkey. The US sought to counter Russian influence in the region and prevent Iran from gaining a stronger foothold in Syria. The US also wanted to protect its allies in the region, including Israel and Saudi Arabia, from the spillover effects of the conflict.
