More like they struck Syria as retaliation because they couldn't go for Iran for whatever reason, but made a fatal mistake.They're counting on Russia being too busy to serve them their just desserts.
Russia hasn't decreased it's activity overseas just because of the Ukraine war. They don't even need to fight officially to make life for Israel much worse. Theres a too large power gap, unless US goes all in on the ground for Israel.
It all depends on if there were any Russian casualties. I'm not counting out that it could be a resistance psyop to get/justify Kremlin funding/support.
