One of the comments from my previous post on unilaterally drawing lines a map showing what I described. I managed to produce crude maps of the areas north and south of Route 55 with a rough line showing the division between what I would annex and where I would withdraw. I am not hard set on the exact location of those lines. However, one thing that is clear is that inside of those two perimeters, there are many places with Arabic names, and outside there are just a handful.
One of the justifications for calling for Israel to eventually withdraw from the settlements is that aside from the settlements west of the security barrier, the settlements are surrounded by Arabs. As these maps show, that is true inside the perimeters, but not for the Jordan Valley and not as clear for Route 5 corridor.
