And what unusual did you see in the fact that the Ukrainian special forces of the Main Directorate of Military Intelligence of Ukraine (HUR), together with the Syrian rebels, destroyed the Russian military in Syria in March 2024?
Calling ISIS terrorists "Syrian rebels" doesn't change their nature and the cooperation between Ukraine and these terrorists has been to attack the Armed Forces of Syria in order to destabilize the country even more, specially in Western Syria to keep them busy domestically and prevent them from looking at occupied Golan heights. The part of Syria soil that is under occupation by another terrorist organization called Israel.
Bottom line is what HUR did here and in a lot of other cases is a clear violation of a dozen international laws and it was an act of war against another sovereign nation called Syria. Russia being there does not give Ukraine any permission to attack Syria forces specially when the attack is in coordination with the terrorists.
