Now, considering that at first, for at least 2 days, the media reported that the bombs did not go off simultaneously but over a time-span of approximately 50 minutes...

... how did this person know that the bombs had gone off simultaneously and that there was "sophisticated choice of timing as well as near-perfect execution"?

Please read the following, quoted from Efraim Halevi's article, written(?) and published on the same day of the attacks:-

The multiple, simultaneous explosions that took place today on the London transportation system were the work of perpetrators who had an operational capacity of considerable scope. They have come a long way since the two attacks of the year 1998 against the American embassies in Nairobi and Dar-Es-Salaam, and the aircraft actions of September 11, 2001.

There was careful planning, intelligence gathering, and a sophisticated choice of timing as well as near-perfect execution. We are faced with a deadly and determined adversary who will stop at nothing and will persevere as long as he exists as a fighting terrorist force.

Amazing knowledge of the careful planning, intelligence gathering and sophisticated choice of timing, let alone his claim of "as well as near-perfect execution".

What do you think he means by "near-perfect execution"? How would he be in a position to know the attacks were executed near-perfectly and not imperfectly or perfectly, on the very same day of the attacks? Did Efraim Halevi know what perfect execution should have entailed?

I find these claims, published on the very same day of the attacks, very revealing and thought-provoking.

Now take a look as he proceeds to tell another nation's people what they must do, another sign that this script was already prepared:-

There will be supreme tests of leadership in this unique situation and people will have to trust the wisdom and good judgment of those chosen to govern them. The executives must be empowered to act resolutely and to take every measure necessary to protect the citizens of their country and to carry the combat into whatever territory the perpetrators and their temporal and spiritual leaders are inhabiting.

The rules of combat must be rapidly adjusted to cater to the necessities of this new and unprecedented situation, and international law must be rewritten in such a way as to permit civilization to defend itself. Anything short of this invites disaster and must not be allowed to happen.

Quick-thinking or what? Did Efraim Halevi's psychic abilities allow him to establish all these things about the bombings and the bombers, when for approximately 2 days it was not known the attacks were simultaneous and employed a sophisticated choice of timing and that they were not "perfect" but "near-perfect" because of the bus incident?

Please bear in mind that news regarding how the bus bomb or bomber might not have gone according to plan came out after this article was published.
