What seems to be the loss of a huge territory by ISIS in Southern Syria and Western Iraq is just the loss of some desert outposts, sadly.
In Southern Syria the US-backed and Jordan-based New Syrian Army has captured the al-Tanf border crossing from ISIS, but overall success has been limited so far. https://en.wikipedia.org/wiki/New_Syrian_Army
In Western Syria the Iraqi Army and allies have made progress in the densely populated parts of Anbar province (Ramadi, Fallujah etc.) which has allowed it to take back some desert outposts.
But maps like these can be really deceiving. Optically they give too much value to deserts and wasteland on the one side, and on the other side important devolopments like the encirclement of East Aleppo, the SAA progress in the Damascus suburbs or the future capture of Manbij by the YPG are barely visible.
Thank you very much for this information!
Also, though, off-topic, but out of curiosity--given your
extremely large amount of knowledge about this topic, can you please respond to this question of mine here?:
