Of course. They captured an important city yesterday, and they know they will have a way to the sea with Lebanon. A country that before the rise of Islamism had a huge Christian and even a big Jewish population. They were its economic engines, btw.
I knew a lot of Lebanese Christians who had fled, and a few Lebanese Jews, when I lived in a place with a heavy immigration from the country (decades ago - this has been going on for a long time). They were wonderful people and it’s tragic that it has finally come down to this.
Islam is incompatible with modernity.
