The Palestinian groups are self sufficient to an extent and recent reports show they are not reliant on Iran as previously thought. That said, a tactical coordination and communication with the Shia group in Lebanon is a necessity at the moment and there are Palestinian groups in Lebanon there. Iran is still needed for certain things.
I consider it hypocritical to say Palestinian groups are completely forbidden to work with Shia groups when the Saudis called upon USA to stop Saddam invading and this was done with the consent of some of their scholars(1 million Iraqi children dead under USA sanctions). From a Sharia perspective, these cases are judged by a case by case basis and there is no prohibition under Islamic law completely preventing working with Shia under the common goal of thwarting an invasion.
You are coming from an idealistic and emotional perspective. The Sunnis in Sham and the wider Middle East are going to have come to some kind of political solution with Shia groups to not strengthen the Zionists and secondly to stop the stem of the current failed state trajectory. This is idea of wiping out Shiasm and not including them in a future political settlement of those states is a complete nonsense and it’s actually laughable when it comes from Somalis. Even the Saudis know this, hence why they have opened talks with Iran and gave some concessions to the Houthis.
Taliban have made some changes to their policies to the Shia minority in their country. They’ve realised you can’t antagonise such a large minority who may become fifth column and be used against you. This is real life state building, something some of you guys are unable to fathom because you read Kitab Taw-heed, and you think every religious/ political verdict can be 100 percent implemented according to the literal fatwa of a few Saudi Sheikhs.
