the logic that netanyahu said he would build, therefore he must, also dictates that if ahmedinejad says he will destroy israel, then he must persist regardless of what the world says, in order to preserve his credibility. "survivability?" israel would be better of without right wing maniacs in the ruling coalition anyway. fairness? fair to who? whiny settlers who see themselves as victims? and how are the palestinians not required to do anything? isn't an almost virtual end to terrorism from the west bank enough? as for reason's not to build, there's one that's more important than all the drama about "delegitimization" (the only party delegitimizing israel is its governments, continually pursuing their illegal and inhumane policies in the territories). that reason is that the land is not israel's; it was conquered and occupied illegally and the lack of representation for its residents makes israel an apartheid state now, not ten years down the line; and israel has no right to build in the territories period. a concession would be giving back some of the land designated for the arab state in 47, but not building in the territories is a legal and moral imperative, not a generous concession.
