Or maybe the Philistines. The Palestinians have lived in the area for too long for you to completely disregard their interests. The land has been continuously called Palestine since Roman/Greek times. Though they speak arabic, it is widely believed that the arab explosion in the middle of the first millennium did not replace the local peoples, but, rather, the locals adopted the language. The Palestinians of today (not including arabs who have moved there recently) may be the direct descendents of the Philistines, who have lived in the area just as long, if not longer, as the Jews.
I'm not saying the whole area should be Palestinian, but it shouldn't be entirely the state of Israel. Interestingly enough, Jordan covers about 75% of the Palestinian homeland.
BTW, Gaza was an ancient Philistine city from the late 2nd millennium B.C., so they have strong claims.
