Contradicting Trump's claim, France's defence minister said on 20 December that IS had been weakened but not been wiped from the map in Syria and that the fight to defeat them definitively in their remaining pockets needed to carry on.

Saying that the Taliban and Islamic State terrorists are "fighting each other" in parts of Afghanistan, he said he told the generals, "Why don't you let them fight?"
In response to the uproar, Trump national security advisor John Bolton will soon visit allies Turkey and Israel, which each have their own complex goals in Syria's multi-dimensional civil war.
Bolton's spokesman, Garrett Marquis, said in a statement Monday that Bolton will be joined in Turkey by Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, and James Jeffrey, the secretary of state's special representative for Syria engagement.
