The F4E won’t be used as fighters, and I don’t think the Turkish pilots will be calling in sick.
I’m not saying the Turks are great fighters, but they are not Arabs.
Yes the Israelis did a lot of upgrades for the Turks in prior days, and that gives them an understanding of Turkish capability. Not a bad thing to have in your pocket.
Per being a smart move for Turkey? Well, that is in the eye of the beholder I suppose, and the beholders in this case are Islamists who care more about positioning in the Islamic world than in the Western world.
I don’t think air or naval threats are too worrisome, but a large ground war against a determined, larger foe would be hard for Israel to stop conventionally. Especially if Egypt jumps in. Look out if Turkey “solves” the Syrian issue, by moving in to oust Asad and set up a peace keeping force.
Out of curiosity, how would the Israeli-Cyprus gas fields involve Russia? I’m unaware of any direct connection there.
