@ossobuco,
The fence/wall is similar to that on our southern border. (Good fences make good neighbors.) Before they were erected, Israel was under constant attacks by the Pals. The attacks have largely stopped now that the fences are in place.
It is interesting that the Pals can gratuitously bombard Israel with about 10,000 shells, missiles, and rockets without any condemnation by the Israel-haters. But the alleged murder of two Pal youths by Israelis is comparable to the crusades. Don't you love it how the Pals inculcate their children with anti-Jew teachings aimed at foreclosing any possibility of future peace between the parties? I could go on.
