The reason why it is difficult for US special forces to be kicked out of Syria
US forces entered Syrian territory
After the self-proclaimed Islamic State (IS) rebels were defeated in Syria, the US still maintained more than 2,000 special forces soldiers in the oil-rich area in the east of the country.
In theory, pro-Syrian government forces are overwhelming in numbers enough to defeat or repel US special forces from bases in eastern Syria.
The US special forces unit stationed in the town of Deir ez-Zor in early February was attacked on a large scale by pro-Syrian government forces and Russian mercenaries.

The US military is maintaining a powerful air force at many large bases in the Middle East, ready to launch sorties to destroy targets and gain air superiority when receiving requests for fire support from special forces.

Without support from regular Russian or Iranian military forces, militia or mercenary units mainly equipped with infantry weapons and tanks and armored vehicles cannot cope with aerial attacks.

Iran has about 70,000 fighters from the Islamic Revolutionary Guard Corps deployed in Syria, along with a large number of missiles near the border, but they face the risk of massive retaliation if they attack these units.
Meanwhile, the Syrian army will likely not directly challenge US special forces, as it is struggling to regain territory from Muslim rebel groups.
In early March, the US announced its intention to have a long-term presence in Syria to control strategically located oil wells in this country.
