"I was surprised that Nasser decided to place his troops so close to our border. He must have known the grave danger into which he placed his forces. Having the Egyptian army so close allowed us to strike and destroy at any time we wished to do so, and there was not a single knowledgeable person who did not see that. From a military standpoint, it was not the IDF that was in danger when the Egyptian army amassed troops on the Israeli border, but the Egyptian army." Israeli General Matti Peled, in the high command during the Six-day War in Peled, Miko. General's Son: Journey of an Israeli in Palestine (pp. 67-68). Just World Books. Kindle Edition.
“The armies were extremely ill-matched. Israelis, through their history, have tended to see themselves as the “weaker side,” their army smaller and less well armed than their Arab enemies. The truth in 1967, as at other times, was different.” Benny Morris, Righteous Victims, p. 311. Benny Morris is one of Israel’s most prominent historians
“American intelligence accurately predicted that Israel would defeat any possible Arab coalition within a few days, perhaps a week….” p. 310
“The Arab armies were mostly professional forces, relatively poorly trained, and not properly mechanized. The Egyptian army suffered from a basic weakness owing to the politicization of its command echelons, which resulted in the appointment of incompetent and inexperienced senior commanders, and structural weaknesses that were to prove fatal in wartime.” p. 312
“The Six-Day War was in all essentials, a clockwork war carried out by the IDF against three relatively passive, ineffective Arab Armies….Throughout, the initiative lay with the IDF; occasionally the Arabs ‘responded’ to an Israeli move; most often they served as rather bewildered, sluggish, punching bags.” p. 313
And the Satmar Rebbe knew it all along:
Satmar Rebbe(Divrei Yoel Behaloscha page 304): Would you even imagine that there would be empty headed fools that while they call themselves religious but the smell of heresy wafts from their mouths and they fool the whole world with their announcements about miracles [during the Six Day War] – G‑d save us. If in fact these were miracles it would have been much worse. That is because there is bitter retribution to the Jewish people when G-d does miracles from the aspect of evil as the Maharal mentioned before stated. However in truth there were no miracles here at all [concerning the Six Day War]. It was simply a natural occurrence as can readily be seen from the discussions in the newspapers that it was assumed that [Israel] would be victorious. I have already stated that I am fearful – G‑d forbid – for the time when actual miracles are done for them. If at this time when in truth there were no miracles and yet this great evil befell them, then surely if there had been miracles done for them that it would have brought about severe suffering as we mentioned above. From this we see the extreme degree of their cruelty and evil. That even though it was reasonable that [Israel] was going to win the war, nevertheless the Jewish people were in great danger. Nevertheless they placed the Jewish people in this danger for the sake of their glory and for the sake of their governing. Because it was obvious to those with understanding that [Israel] had the ability to completely prevent the war. There were a number of alternatives and circumstances regarding preventing the war, but this is not the place to go into detail. Nevertheless someone who has eyes will see that there is no doubt about this. In fact it was the filth of heresy that blinded their eyes and made them act in an irresponsible and irrational manner.
