What is really needed is a double wall similar but not the same as in the West Bank. One Wall on the Israeli side and another on the Gazan side. Set each back 10 meters from the border and mine and electrify the middle. No line of sight for either side. No free passage for either side, except at agreed crossings. No watch towers unless agreed and equal on both sides. No Gazans shooting into Israel, no IDF shooting into Gaza. This happens far too often.
