That's the opposite of what Derek is saying in his newsletter:

Events in Syria are moving farther and faster than they have at any time since insurgents swarmed into Aleppo city over the weekend, and the time remaining for Bashar al-Assad as Syrian president may be closer to hours than months or years. Hayat Tahrir al-Sham and affiliated groups followed up their seizure of the city of Hama on Thursday with a rapid advance all the way to the outskirts of the city of Homs by Friday evening. They’ve obviously met little resistance from the Syrian military or the residents of the towns and villages they’ve swept through along the way, and it’s unclear how much of a fight they can expect in Homs. If they’re able to take that city—and there’s no reason at this point to think they can’t or won’t—the main question surrounding this offensive will shift (if it hasn’t already) from “how much longer can the insurgents keep this up?” to “when is Assad going to leave the country?” That’s assuming he hasn’t yet done so—very sketchy claims are circulating via social media that he’s already fled.

A rebel seizure of Homs would cut the main direct route between Damascus and the coastal northwestern provinces of Tartus and Latakia, which are home to Russian military bases and the Assad family’s main social support base. But it is not the only front on which the Syrian government is now foundering. To the east, the US-backed Syrian Democratic Forces group took control of the city of Deir Ezzor on Friday, which is a huge development if one that is less immediately critical for Assad. Deir Ezzor was the Syrian government’s main hub in the eastern part of the country and its loss leaves the SDF in a much stronger position though it’s now facing heightened threats from Turkey-backed rebel groups. To the south, insurgent factions have been battling security forces in Daraa province and late Friday the Syrian Observatory for Human Rights reported that they had taken control of the city of Daraa. The Jordanian government closed its only border crossing into Syria on Friday due to militant activity on the Syrian side.

The United Nations estimates that some 370,000 people have been displaced since the rebels began their offensive last Wednesday, and it’s warning of the risk that up to 1.5 million might eventually be displaced. This is happening so quickly that I’m sure there’s been no serious consideration given to humanitarian needs, and displacement camps are predominantly located in northern Syria, in territory controlled by the groups that many of these people are fleeing.

That 370,000 figure may not include the tens of thousands of predominantly Alawites who have fled Homs over the past day or so, according to the SOHR. Their flight highlights perhaps the biggest concern as HTS expands the territory under its control—namely, how this jihadist group, which has shed its ties to al-Qaeda but not necessarily its ideology or its intolerance for minority groups, aims to treat its new subjects. HTS appears to be going to some lengths to present an image of liberality and good governance in Aleppo as a demonstration of what it would do in the rest of the country, but that could well prove fleeting. As The Washington Post reported on Friday, Christians in Aleppo seem pleased with their treatment so far but are concerned that there may be another shoe that will drop once things quiet down. Much less has been reported about HTS’s intentions toward other groups, but the evacuation of Homs’ Alawite population suggests that community is deeply concerned.
