Countries that sell weapons to supposedly friendly nations, may one day fire those same weapons onto those who sold it to them. Thus two points should be considered in what Turkey is doing as of late. The first is that not every Turk is against Israel. Most have no interest in fighting Israel. The other being that the Turkish army is in a dilemma as to what to do if they receive the order from Erdogan to go to war against Israel. For now, things appear bleak, but Turkey would find itself on the wrong end of things if it ever did make such a move. Way before war would be declared, I believe that Erdogan may well be overthrown by the Turkish pro-Europe majority.
