BS.
Arab countries have learned the hard way over the decades that they can't fight the mightiest and the richest alliance in human history for Palestinians without destroying whatever prosperity exists there. And it is not just Arab countries: Pakistan, Turkey, and more remote Muslim countries are also like that. They WANT to help but the repercussion would be so huge that they dare not. It is not that Arab/Islamic countries had not tried before-- Pakistanis even fought against Israel in 1973 in a limited capacity.
What's going to happen to the economies of Arab/Islamic countries who depend on the commercial interests with the West when an outright war breaks out? Unemployment, chaos, and pushing back their economies decades.
Only Iran--and that too in a calculated, reluctant way is willing to put itself in great danger by helping the Palestinians.
PS. My personal viewpoint remains that this conflict should be escalated, widened and prolonged. I don't think Israelis would be able to stomach the losses from that. That will end this conflict once and for all: Either Israelis bring up another Rabin for some compromise or Israel will vanish. But it is not my call to make, sitting at safe distance.
