well, in looking at other pics of the israel wall, i learned more about it all anyway. you're making me do some homework, gator!
Israel’s Wall
"
It is part wall, part fence. Out in the countryside it is mostly a wire fence with razor wire, a ditch and electronic sensors. In town and city it is mostly a concrete wall up to 8 metres high, with graffiti and watchtowers. Pope Francis stopped at the wall in Bethlehem to pray. Barack Obama did not."
so saying LOOK AT ISRAEL is only partially correct. they don't have a wall around everything either. WWZ or not.

the ones they do have are focused around the immediate area and then done.
what i also found interesting is that according to this article, israel is building the wall on land NOT their own. need to go dig up more history here if i get time today and research this for myself.
