Afaik there’s no evidence that al-Sharaa ordered those attacks on Alawites.

One thing to understand is that Syria is in an extremely unstable situation at the moment. Al-Sharaa is leader of an already fragile group of militants/terrorists that’s barely held together. He can’t afford war with Israel, because the resulting counter-attack might shatter his government. He’s not fully in control either, leading to these horrible attacks on minorities by certain wings of the armed forces. Militants he has less control over still seek revenge against the Alawites for their support of Assad.

He basically needs to stabilize the country, centralize control and demonstrate that Syria will rapidly improve under his rule. That is no easy task, and it’s imo not surprising that the civil war is not over yet in certain parts of the country.

IIRC the EU put as precondition of sanction relief that he gets the militants under control and stops the attacks on minorities. I don’t know for certain that he will or even wants to (he might be a moderate amongst militant Islamists but that’s still fairly extreme), but I also don’t have conclusive evidence that he won’t.
