"Does Syria jump in here and open a third front."

Not a chance.

Doesn't Syria have to protect its eastern border since the US is there?

Does Syria jump in here and open a third front

In my opinion Syria doesn't want to, because they know they'll loss.
Iran is trying to convince Syria to take action against Israel.
I believe Iran is attempting to keep the world focused on the Israel theater
so they can maybe get a nuke built while attention is shifted.
Iran also knows Syria would be the loser in a conflict with Israel but they really don't care about Arab nations. They'll use them if they can.

The next few days should prove to be interesting.
