On the morning of October 7 — a date that will long be marked as one of the Jewish people's darkest days — Israel's security concept crumbled as Hamas terrorists streamed through, over, and around its Gaza border fence.
Israeli leaders believed that the fortification, an NIS 3.5 billion ($1.1 billion) project that took over three years to complete, would provide a defensive shield around its citizens on the border.
"This barrier, a creative, technological project of the first order, denies Hamas one of the capabilities that it tried to develop and puts a wall of iron, sensors and concrete between it and the residents of the south," said then-defense minister Benny Gantz at a ceremony marking its completion in 2019.
As videos of the calamity on Saturday made painfully clear, the fence did next to nothing to stop the invasion.
