To go out on a limb and give them the benefit of the doubt, the map is labeled "The Arab World" and their does seem to be a border (although you have to look closely to see it) between what would be Israel proper and the West Bank. In addition, they do at least pay lip service to the existence of Israel - beside their delusional vision of a peaceful Palestinian state.
That's what I thought at first glance. I enlarged the map, and what might appear to be a partial border, there's no border with Gaza, looks to me to be the Dead Sea and Jordan River. The border with Jordan a single state would enjoy.
The clincher for me, the non Arab Ethiopia and Western Sahara are unnamed, but depicted in white, there's no white where Israel should appear. Given the many incidents over the exclusion of Israel from maps, something a palestinian group would be well aware of, I think they're sending a message. A "deniable" message, to be sure, but a message of solidarity.
It's the Arab World. And what would be Israel is hardly a pin prick on that map.
And yet, comparing all that territory, according to Rice:
"there could be no greater legacy for America than to help to bring into being a Palestinian state"
One more Arab state. And if its being eviscerates Israel, well there is no greater legacy for America.
