I am in my hubris quite confident that this is the only prudent policy for Israel to pursue, both from a security and from a PR standpoint.
It will reduce the number of deadly attacks on Israeli civilians, but it won't prevent many. Besides, walls can't stop incoming Katyusha's or mortars that Pallies will be firing into Israel. The conflict will continue until one of the sides is completely defeated.
And one of these points was the difference that exists between leadership and hectoring. To see the meaning of the latter, retain the first words of every sentence --- this explicates the structure of your post --- and to obtain:
Israel should And it should It should And it should It is the only It must It must the only thing better step up in a hurry.As for the former, that is, leadership, it is constrained by the reality of things, the very reality that you choose not to see because it will deprive you of the armchair-general position that you appear to occupy so comfortably.
Well, I guess I just took a risk similar in magnitude to yours --- I repeated myself. Since you prefer only one-way communications and hectoring, whereas I tend to like a discussion, I shall take another risk and end this discourse for now.
I do hope you will not take it as offense. Have a good Easter Holiday.
