30 years ago I was an instructor at the Armour Academy when Sadat came for his historic visit (as I reminisced here). During the visit the staff did everything possible to spend as much time possible watching the visit on TV; our trainees mostly continued training as usual.
Achikam is now at exactly the same stage of training that my soldiers were at then. Without wishing to divulge any military secrets here I can say that his unit has interrupted their training, and has joined the effort of ensuring there are no terror attacks during the week of the summit.
I guess someone is less optimistic now than then.
