I believe that Israel has likely communicated with their neighbors that any large scale action from their areas will be dealt with harshly.
I would think that Syria has its hands full, and Jordan wants nothing to do with the Palestinians. Egypt would probably want to join in...but they are going to be dealing with a million refugees in the next week. Logistically..their tanks would not be able to move towards Israel.
So...no. Syria will stay out of this round.
If Syria wants to continue to exist they’ll stay out of it.
I wonder if Vlad will keep Iran and Turkey on ice in those northern areas?
He may just be waiting for an opportunity to get involved.
I don’t think Assad wants to get involved. Militarily, he’s got too much on his hands already, economically, he’s getting rich in the ME drug trade.
