Israel's Most Costly Error?

It's preemptive strike against the Arab states in 1967? No. Egypt's decision to close the Straits of Tiran, its mobilization of troops along the border with Israel, and the bellicose language coming from Egypt and Syria were all a more than adequately sufficient justification for Israel's action.......The fact that Israel annexed the West Bank from Jordan during this same conflict? No. Israel repeatedly made peaceful overtures to Jordan and pleaded with them not to engage in hostilities. It was only after Jordan started shelling Israeli civilian populations and later sent in its air force to bomb key residential areas that Israel eventually responded; bombing Jordanian air-fields and, yes, seizing the West Bank.......In my opinion, the biggest miscalculation that Israel made was its failure, post the '67 War, to adopt the Alon Plan. This plan, which was put forth by Labor Minister/General, Yigal Alon, had Israel withdrawing from all Arab population centers and from most of the other territory as well. Yes, it did call for some of the land to be annexed but only enough for defense and to maintain "territorial integrity". The way that I see it here, had the Israeli's chosen this route, they could have a) solidified their defenses and b) avoided the embarrassment of having to occupy another group of people for multiple decades (world sentiment might have actually swung to their advantage)....But, hey, hindsight is 20/20, right?
