Apart from a few outlying territories, the Syrian War is for all intents and purposes over. The rebels are defeated and Assad endures. The war being over doesnt appear to impact the US plans however.
Roughly 1,000 US troops are deployed in Syria, and officials say they have no plans to end that presence, or to lift sanctions aimed at regime change in Syria.
During the Trump Administration, US forces shifted focus to an oilfield with a new mission to take the oil. Illegality of that aside, it appears that plan remains in place.
John Kirby says the US goal in Syria is solely to combat ISIS, an interesting position since the US almost never fights ISIS at all. Recent anti-ISIS operations were launched by Syria and Russia.
