Old school communications. Used runners like we did in WWI.
There’s a huge lesson to be learned here....keeping 2 million people in a fenced area in large concentrations, knowing you can deny them food, water and energy whenever you feel like it, has dire consequences.
Turns out if you keep people in such conditions, they have nothing better to do than to plan their revenge.
People who have no hope are hard to fight because they don’t care if they die.
That’s what I was thinking. Very low tech solution in a high tech environment.
Runners, word-of-mouth, written orders.
Reminds me of communication during our Civil War. Perhaps Hamas even has spies in the Israeli government.
At any rate, they caught Israel totally off guard.
