The PMU — which is fighting alongside the Iraqi government forces — seeks to reach and take control of the border between Iraq and Syria. This comes against the wishes of the United States.
The movement of the Syrian government forces toward the southern border indicates that they intend to get close to the al-Tanf base located in the area between Syria, Jordan and Iraq, where the United States trains Free Syrian Army (FSA) elements.
Retired Lebanese army Brig. Gen. Elias Hanna said in an interview with Al-Ghad Al-Arabi television May 12, “The US wants to control the Iraqi-Syrian border.”
A member of the FSA media office told Almodan newspaper on May 19 that “the Syrian government and Iran seek to control the crossings of al-Tanf and al-Walid to open a channel between Iran and Syria through Iraq. This would spell great clashes on the Iraq-Syria border.”
The United States wants to prevent any contact between Iran and the Syrian government that could facilitate the supply of arms from Tehran to Damascus through Iraqi territory, and this is why it exerts all possible efforts to prevent the PMU and the Syrian government from controlling the borders between the two countries.
