Yayir Lapid who was at the time the leader of the anti-Netagnao camp said he wouldn't sit with the Arab led parties and he ruled out any possibility of creating a broad enough coalition to defeat Netanyahu. In order for Palestinian citizens of Israel to join a coalition addressing the occupation has to be on the table. It's not clear to me that they understood that even now. You at best you'll have clientelism like Rahm where the leader of Rahm on Surabas basically agreed to accept Israel as a state that doesn't provide equal citizenship in exchange for what he could gain from the Zionists Basically.
