Came here to write that too. BUT on a positive note it means they have plenty of ammo. And given the speed of their advance we can't complain that they are lazy...
Genuine question, If these rebels are actual offshoots of Al-Qaeda and willing to behead their advisories (including a young boy), when they lay hold to the state machinery won't they commit Assad level atrocities?
Atrocities yes, but it's actually difficult to commit atrocities at Assad's level. They'll have to work at it. Let's hope they're too busy to put in that effort
I find it hard to believe that these rebels won't commit war crimes when they have access to modern military equipment and western backing. If I am wrong please correct me.
Maybe. But their ranks have been "diluted" from those days--they come from a mix of backgrounds, viewpoints, etc..
It could be as you say, but it could end up being like the Azov Brigade in Ukraine where they transcend their dodgy origins.
The first test will be how they interact with the SDF.
