Su-35s engage F-16s in Syria and plan to confront them in Ukraine.

Russian Su-35 pilots have been conducting "aggressive maneuvers" against American F-16 fighters in Syria, with at least 85 similar incidents reported in recent months. While Russia claims their pilots are being harassed by US fighter jets, they have not provided any evidence. Analysts suggest the aggressive actions are due to the US military's illegal presence in Syria and the upcoming challenge of facing F-16s in Ukraine. The US has sent F-22s to the region to oppose Russian air aggression, but their presence may not be effective due to political reasons.
