The reports I saw claimed the Russians in Aleppo fled along with the Syrian government forces, leaving tons of Russian equipment for the rebels. It is not entirely analogous to Kabul 2017 since, in this case, the departure wasn’t planned.
correction: Kabul 2021.
These are evil rats Jihadist rebels. But they are doing God's work kicking the Iranians and Russians out of Syria. These rebels came out of nowhere. And all because Israel, decimating Hezbollah, gave rebels an opening. Let's hope they get rid of Assad / Russia / Iran throughout Syria. Some here are biccching that our CIA is helping them. I sure hope so!
