the truth is no state has fought israel on behalf of palestinians except perhaps during 1948 war. arab states have hosted the plo and other palestinian organizations sure but egypt and syria's war in 1973 was caused by israel's occupation of the sinai and golan. assad intervened in lebanon to protect syrian interests and even hezbollah has their own reasons.  palestinians have been supported by various regional powers and groups over the decades but no one is going to fight on their behalf.
