There are 32 miles of border separating Gaza from Israel. Since my first visit to that border in 1984, it’s been heavily fortified, with walls, fences, and surveillance systems backed up by soldiers and law enforcement. That system was overwhelmed in a matter of minutes in the early Sabbath hours of Oct. 7 as thousands of Hamas terrorists breached the border barrier in some two dozen places, pouring out to massacre, behead, rape, and capture hostages in an orgy of violence.
