"The quality of the actionable intelligence may be seriously flawed, that is what happened, I believe, on Saturday," Ford stated. "It should remind us all that just because the Americans and Russians might agree to work together does not mean they are actually going to be very effective militarily against Fateh al-Sham [Nusra Front] or the Islamic State [Daesh]."
Military cooperation between Washington and Moscow is possible, Ford added, but the ground component is more important at the moment, which is up to Turkey and Iran with Russian air support.
The United States and Russian reached an agreement to establish a Joint Implementation Center to coordinate antiterrorism operations in Syria after seven days of calm hat was due to expire on Monday.
Daesh is a UN-designated terrorist organization outlawed in Russia and numerous other countries around the world.
