Your initial post claimed they held no territory which is false. It is of course true that what they hold isnt meaningful its pretty much been a dozen villages for the last year, with the final offensive against them starting only like 2 months ago
Yeah, and in my initial post I said "pretty much", i.e. nearly, but not entirely, complete. They lost Hajin in 2018, their last capital, and they have no territory at this point other than a hardly-noticeable swath of land near the Euphrates River, which is not secure. In a word, they do not control any territory, and have not for quite some time
