Sanmich lives in Israel 😛
exact, but for the last year I'm in the US, so I haven't the slightest clue about who predicted what.
Generally I would say that in Israel, terrorism prevention have demonstrated to be mostly based on inteligence of all sorts, and certainly not on high profile activity around the target.
A bomb can be quite easily intercepted in the stages of preparations. When ready on the carrier, the only thing that can be done is limiting the casualties by some kind of last defense line (check point on the roads, at a mall entrance, etc)
The price at this stage is usually in human lives, but even when we had cases of specific information about a bomb making its way to a certain area and by chance "they" intercepted it through this last line with no casualties, this results in a huge mess on the roads for hours.
when you don't have this last defense line, like in buses or on the streets, well, 99% of the time it's too late...
From my very limited experience, the massive, heavy high profile activity has only a very small contribution to the small and hopefully really important intelligence and prevention activity.
