Guess where them and everyone else is coming as the next phase of this destabilization and fragmentation kicks in?
There are multiple reasons that restrict Israel's scope for action in Syria, despite their ability to project and create an image of them doing whatever they want there. This is clearly propaganda narrative. No country, including the US, can operate totally free and careless in the Middle East.
1. Even though Syria lacks an air force and air defense systems like Iran or Lebanon, advancing further north and engaging the Syrian Army would result in the deaths of thousands of Israeli soldiers. A literal quagmire. A conflict in Syria would be far more challenging than the situation in Gaza, which is why Israeli forces remain in their current position, safely located in a mountainous area.
2. If Syria is destabilized to the point of creating waves of refugees, it will provoke strong reactions from Europe, as the Turks would send them to the EU. Neither the European left nor right will tolerate any Israeli actions that lead to more refugees. This is a crucial issue for them, despite their support for the Israeli government, and Tel Aviv is fully aware of this sentiment in European capitals.
3. The Americans are keen to strengthen their relationship with Turkey. There is a new understanding of Turkey's significance in US foreign policy.
Most decision-makers in Washington recognize that Ankara is vital not just for its geopolitical location but also for its military capabilities, production facilities, technological advancements, influence in Central Asia regarding China, monitoring Russia & Iran, ties with Pakistan, cooperation with Southeast Asian Muslims, foothold in the Balkans and Caucasus, and military presence in Northern Africa, strong relations with South Korea, among other factors. While they may permit Israel to strike Syria if necessary, there will be a natural limit concerning Israeli support for the SDF/PKK.
The US is not just going to step in; the Turks might also return the favor by providing similar help to the Syrian Army, Hizbies in Lebanon, or Huthies in Yemen.
Even though the Israeli military is considered "strong" (due to external support), they have a vast area to defend, numerous adversaries, and are currently worn out from dealing with Iran. Starting a conflict with Ankara is not in the cards.
