The Syrian air force fought in the air, the Shia militia on the ground
The Syrian-Hezbollah operation against al-Qaeda (Hayat Tahrir al-Sham) on the Lebanese-Syrian border is over. HTS has accepted terms under which its surviving fighters, and any civilians who wish to follow, will be bused to Syria's rebel-held Idlib province.
Hezbollah actually offered a similar evacuation deal ahead of the battle, but HTS initially refused. It is believed between 7,000 and 8,000 people will be moved in the transfer which has already begun.
A larger ISIS-controlled pocket remains just to the north of the area now cleared by Hezbollah, but the success of the offensive means that after 4 years al-Qaeda no longer has a territorial presence in Lebanon.
Will the US be sending Syrians and Hezbollah a thank you note? We won't be holding our breath.
