Does this mean the rebels will help Ukraine against Russia ?
Maybe, though they have enough on their plate at this point. I think initially it will be just information on some of the weapons Russians ditched when they ran away.
I wouldn't be surprised if some Syrians, say people who lost family in the snuffing of Aleppo, went to Ukraine to kill Russians though. Out of revenge or out of thanks for Ukraine being instrumental in getting rid of a brutal dictator, whatever. I think we'll see some like the Chechens, after their Russian wars. People with dead families and nothing left to lose, only vengeance to gain.
Gotta give Zelenskyy huge props for this victory though. Talk about humiliating for Russia and Iran. Tehran's been kicking sand in his face by giving Russia drones and support. He waited until the time was right, then responded by sending an axe to remove an Iranian leg. Did the middle east and world at large a favor too. As losses of influence and control go, this was a big one.
You're next Putin, and I can't wait to celebrate it.
