MOSSAD
Takes some intimate inside knowledge to circumvent the security systems along the Gaza frontier.
And, why Gaza?...because it was the obvious choice?
The big question would be, to me, how did they even build up to this attack without being noted. Mossad, in the past, has had numerous agents infiltrating outside of Israel’s borders.
As for the security systems, anything Wifi is highly vulnerable to hacking or simply disrupting. Just broadcast a strong signal at the WiFi frequency and all data and information will no longer pass. Basically blinding the automated security system. Of course, there are other systems, up to and including human sentries. At least one would hope.
But fact is, this should have been known about in advance. That’s the part that’s hard to believe. Unless entities that are there to protect made a conscious choice to NOT protect.
Given how our own FBI has gone rogue, it’s not too hard to fathom that many other agencies have taken on a purpose counter to their original functionality.
