Israel and Turkey will never directly confront eachother under these current governments, especially within Syria. At least not to the level we've seen between Israel and Iran.

Sure Turkey could give the IDF a black eye, even ignoring the US element it serves both sides to maintain a slow moving and low-intensity battle for Syria. To escalate things further on this front would have the opposite effect to relieving domestic pressure on either side.

Even with Iran and Israel we've yet to see them engage in more than single operations since a direct war would be much more unpopular once military recruiters start rounding up conscripts, or a war economy interrupts civilian life. I think Iran is of course less affected by these facts than Israel but there are also other factors at play.
