The Americans are now trying to extinguish the conflict, as fighting between Kurds and Turks, may hinder the implementation of the plans associated with preparing a direct assault on Raqqa. Through a network of military bases deployed South of Kobani and Qamishli, the U.S. continues to drive to Raqqa various military and civil engineering machinery (like SOF and 75th regiment of the Rangers, and for SDF/YPG), but the previously announced time frame of the assault of Raqqa already obviously moved because of the profound losses in the fighting on the southern Bank of the Euphrates, and the lack of heavy equipment, as well as the protracted siege of Tabqa.
