Are there or are there not Russian forces still in Syria? They should bee worried. I wouldn’t mess with Israel.
Biblical prophesy predicts that Russia will move on Israel along with other regional powers.
Yes, there are permanent Russian forces in Syria, propping up Assad, and securing ports on the Mediterranean.
Israel has many business partnerships with Russia, but Russia considers Syria a much closer military ally, and would side with them if/when forced to choose.
Golan Heights is the most likely flash point between the two.
My understandings of a complex area.
