How did Hamas manage to keep this attack a secret from Israel and everyone else? All their plans and communications were kept offline.
...What Hamas did, what their leadership did, was apparently they moved off of the normal modern communications links that we take for granted every day, and went back to what you did in the 19th century: face-to-face meetings, they went and used couriers instead of going in and using the telephone or the cell phone...
There's a lesson in there somewhere.
Onward and upward,
