Sobering that the “dirt-poor” refugees and women and innocent children of Palestine have the resources to fund frogmen, tunnels, underwater depots and exits, and the techniques to use them against Israel.
On the other hand, making it always ever-harder to just walk across the street and kill innocent Jews wholesale means the retail price of terrorism also goes up.
Building the wall to stop illegal aliens will not stop all illegal aliens. But it will make it harder for all illegal aliens, and WILL STOP many illegal aliens who would otherwise walk across.
Drones to alert and A 10s to prosecute
Walls are an old concept, I give you the Great Wall, a bit further east in the Orient. The walls around Jerusalem, keeping to the geography. They minimize incursions, but are effective.
Sorry, left off. The real question is whether one wants to keep the people on the other side of the wall on the other side. Collectively at least, that question is not yet answered. Here, not in Israel who decided to keep the terrorists on the other side. Like Egypt, the Saudis. Walls aren’t an exclusive club, heck, the Vatican still has them.
