He meaning Putin?  The small areas in which Isis remains in Eastern Syria are the areas controlled by the USA and their Kurdish puppets.  Plus a small Isis pocket on the border with Israel, enjoying R&R in Israel and care in Israeli hospitals.  The USA is operating over a dozen illegal bases in a country in which it is an invader - still protecting Isis.  The Russia/Syria/Iran alliance has liquidated about 100,000 Isis mercenaries since late 2015.  Foreign (not Syrian) Isis mercenaries were funded by McCain/Hussein/Israel/Qatar/Saudi money.  The USA actually bombed Syrians and Russians attacking Isis in the Euphrates valley.  USA helicopters have been used to evacuate Isis commanders from areas where they would have been captured or killed otherwise.  The only thing Trump has done to hurt Isis is to stop funding them - which is a good thing.  As for Israel, their latest attack on Syria was a temper tantrum triggered by the ongoing liquidation of the last Isis pocket in south Damascus by the heroic Syrian Tiger Force.  Syrian Arab Army photos show huge Isis ammo stockpiles, big shells labeled in Hebrew.  "Isis" is a nod to Egyptian paganism, also = I.S.I.S. = Israeli Secret Intelligence Service. PS:  Isis murders Christians.  Assad protects Christians.  Easter was celebrated again in liberated Aleppo this year, praise God.
