This would eliminate the influence of the speed of light and would allow mutally equal synchronization between clocks at A and B.
 But this was not, what Einstein had done.
 Instead he had the strange idea, that the time value seen on the rmeote clock would be the time at the remote location.

 Absolutely NOT, there is nothing of that kind in Einstein paper !
 from t_B - t_A = t'_A - t_B
 and (2AB)/(t'_A - t_A) = c
 [i.e. t'A - t_A = (2AB)/c ! What is (2AB)/c if not - obviously -
such a delay (twice the delay actually) you stupidly complain that
it wouldn't have been taken into account ? ? ?]
  From these two simple equations you can deduce immediately :
 t'_A = t_B + (AB)/c
 i.e. time shown on clock A when receiving a signal sent by clock B when
clock B was showing t_B is t'_A = t_B + (AB)/c
 (AB)/c is the delay : the time taken by light to travel from B to A.
 If you cannot spot this at first read it means that your are not a
member of the expected audience of this article i.e. non-morons.
 Which makes your attempt to "evaluate" it as a teacher quite pathetic.

 Je crois qu'il confond le docteur Hachel et le docteur Einstein.   La notion d'anisochronie spatiale, c'est Hachel.
  Einstein et Hachel posent (2AB)/(t'_A - t_A) = c
  Mais Hachel dans son immense génie réfute t'_A - t_B = t_B - t_A ce qui d'ailleurs ne veut rien dire (à la limite c'est vrai pour tous les points situé du le plan médiateur (oh un néologisme), mais à l'exclusion de tous les autres points de l'univers.

Back in 2007 you wrote in a post on fr.sci.physique (*) that Einstein
did not care at all about clocks synchronization in his 1905 paper.
Then I showed you that he did in part I.1. quite explicitly by the way.
When presented the equation t'_A - t_B = t_B - t_A your reaction was that
this equation meant that both clocks tick at the same rate. Which is utterly
ridiculous.
There is no reason to think that you understand such basic stuff better now than
then, quite the opposite actually.
