You know as well as I do, Oliver.
1). First of all, a week later, the Palestinians start a new war of mortars, GRAD rockets, etc., from the just-achieved old borders (or perhaps, more accurately, an old war from the new borders).
2). The continued education of the youth that no greater glory exists than to die for liberating Palestine, and that the newly-achieved state is merely a step towards Israel's total annihilation, as per the 1974 PLO "staged plan", the Hamas charter, etc.
3). Constant rearming, encouraged by Hizbuallah, Hamas, Iran, Syria, etc.
4). A wave of terrorism that will make the "second intifada" look like a joke.
5). Constant claims in the world media that it is all Israel's fault since "the occupation" somehow magically continues.
All this can be safely surmized, based on the 16-year-experience with the Oslo "peace" process and the 4-year experience with the ending of the occupation in Gaza.
What then? Who knows. Either the destruction of Israel by stages, as planned -- after which the world will simply accept the newly-formed "greater Palestine" as a fait accompli and forget within few months about the little genocide of the Jews that it caused. The "human rights activists" will either ignore the genocide or justify it.
Or else, perhaps unlikely, another Nakba, due to the same reason as the original one (to wit, the Arab desire to throw the Jews into the sea) -- after which the world will blame Israel once more for the next 60 years, and the Arab "brothers" of the Palestinians will keep the Palestinians in camps as "refugees" for another 60 years, in an attempt to try the whole thing once again. With the enthusiastic support of the "human right activists" of course.
(Resettle the refugees? Just like millions of other refugees were? Note that it makes little sense to call a third and, by now, fourth generation "refugees" just because their Arab "brothers" refuse to resettle them anywhere else but where they can destroy Israel? What! And give up the dream of throwing the Jews into the sea with them! Who are you, some kind of Zionist apologist or something?)
