And I think it wasn't so much that the Arabs were poor military stategists, I think the ordinary soldier didn't care enough about their cause. Sure there were extremists involved but most Arabs were forced to participate when it became a "with us or against us" situation. They weren't prepared to die for the cause. The Israelis had no choice but to fight to the very last.
At a military history forum I post on, the issue concerning the quality of Arab militaries came up in the course of a wider discussion about what if the Cold War turned hot. Here's what one Russian member posted:
"My grandpa was among the two divisions of military advisors that were sent to Egypt, and he was of a very low opinion of the Arabs as soldiers - corrupt and elitist officers' corps that all but negated the effect of Soviet training and soldiers that hardly had a notion of what "disipline" was. He was inspecting AA rocket installation not far from the Suez canal and he would sometimes find the Arabs having siesta in the midday with no one staying on duty."
In the aftermath of the Six Day War, the Soviet military did conduct several studies into these issues as to why the Arabs did so poorly. They concluded that the Arab militaries did indeed lack significant discipline and failed to properly conduct themselves in accordance with the weaponry and tactics they were taught.
OP, you need to look at Sun Tsu's Art of War. He says thaat when men stand on death ground, they fight with abandon. It means when you beleive you are going to die, you fight at your peak. The Israeli's stood on death ground, so they fought hard.
