For twenty years, Israel relied on a security barrier to prevent the suicide bombings and shootings of the Second Intifada. It worked. While ninety percent of that barrier was not a concrete wall, but a high-tech fence—cameras, sensors, patrol roads, and layered detection system – it still reduced terror attacks from the West Bank by over 90 percent. Israelis and the Stateless Arabs from Palestine (SAPs) rebuilt their lives believing that a fence, not a fortress, was enough.

Then came October 7.

Hamas gunmen bulldozed, exploded, and burned their way through what was—on paper—one of the most advanced border fences in the world. They murdered, raped, tortured, and kidnapped civilians in a genocidal assault that shattered the central premise of Israel’s security doctrine: that a fence and technology could stop an army of terrorists long enough for the IDF to respond.

That assumption is gone.

If a similar surprise assault were launched from the West Bank near the country’s major population centers—Tel Aviv, Jerusalem, the coastal cities—the casualties could be catastrophic. Israel is nine miles wide at its narrowest point. One breach is not a tactical event. It is an existential one.

The Barrier Must Change Because the Threat Has Changed

A fence can be cut, rammed, or climbed. A reinforced, multi-layered wall—physical, electronic, aerial, and subterranean—is a different proposition. The lesson of Gaza is not to abandon the idea of separation, but to upgrade it to match the enemy’s capabilities and intentions.

Israel does not have the luxury of guessing whether future attackers will try to slaughter dozens or thousands. The security architecture must assume the worst case—because the worst case already happened.

Disarming Militias Is Not Just for Gaza

The world is focused on disarming Hamas in Gaza. It must also confront a parallel obligation: militant groups in the West Bank cannot remain armed if there is to be any political horizon, for Palestinian Arabs or Israelis.

If Gaza is demilitarized but the West Bank is not, the threat simply shifts geography. The barrier is not a substitute for disarmament. It is a second line of defense, not the first.

Lasting security requires:

1️⃣ Complete disarmament of organized militant groups seeking Israel’s destruction.
2️⃣ Security control capable of preventing re-armament.
3️⃣ A barrier strong enough to make a surprise attack militarily unachievable.

Without those three components, diplomatic talk of a “future Palestinian state” is not a peace process—it is a gamble with tens of thousands of civilian lives.

A wall is not a symbol of failure. It is the price of survival when the alternative is the erasure of towns near the 1949 Armistice Lines with Jordan.

A move towards coexistence between Israelis and Palestinian Arabs cannot be limited to the threat from Gazans but from West Bank Arabs as well. Disarmament of West Bank Arabs and an upgrade of the security fence must happen now as well.

Peace requires trust. Trust requires time. Time requires security that cannot be breached in seven minutes by men with bulldozers and grenades and genocidal jihadi rage.

Until a day comes when coexistence is real—not chanted, not theorized, not negotiated—Israel must ensure that no armed faction can cross its border. The time to implement that plan is now.
