Israel's end game is founding a vassal PKK state that will be a friendly vassal, guarantee Israel's security, and act as a buffer against Iran. Such a state can gain land from Syria, Turkiye, Iran, and Iraq which means those countries will be no threat to Israel for a few centuries. Even if it can't gain land from Turkiye and Iran a PKK state will be very useful to keep Turkiye in check and waste its energy. They will carefully arm that state with weapons that will be no threat to Israel but will be enough to deter a possible attacker. Iran's end game is Iranian control of Syria and completing the Shia axis of Iran-Iraq-Syria. Iran sees Turkiye as the biggest threat to this plan and wants to use PKK against us. Iran has firm control over a good chunk of PKK and the Talabani clan.
Russia wants to keep its bases and control over the regime. In that regard, it is in competition with Iran.
Israel is very concerned with Turkish technology developments. All of the F-35, F-16V, YPG, and Eastmed shenanigans are organized by Israel and the Jewish lobby in the background. After the Mavi Marmara incident, Israel switched to another mode even though Israel doesn't see Turkiye as an enemy it recognized us as a competitor/potential threat and started to act accordingly. Israel wants to weaken Turkiye so that it stays harmless to the state of Israel. This is done in two layers
1)Keeping the QME(Qualitative Military Edge) of Israel on the top while eroding the QME of Turkiye by embargoes and strengthening other players. A Turkiye that has a military technology parity with Israel is considered a dire threat.
2)Isolating Turkiye. Eastmed forum, coalition against ISIS, a possible middle eastern "NATO", a PKK state in Syria and Iraq that has the potential to add Turkish and Iranian lands.
