Once again there's a narrative about a group of primitive savages from the desert somehow bypassing the most advanced security system in the world.
It was not an inside job that involved Israeli traitors. Years ago a treacherous, greedy US president gave Syria the technology to dig massive underground tunnels — those tunnels have been made under the borders and into the land of Israel. That's one way they got in; also, the use of weaponized paragliders.
The USA, for instance, has dug out thousands of miles of tunnels under the USA with railways and entire cities deep beyond the reach of ground penetrating radar – courtesy of the same past president. So has the Middle East.
Who was the president?
