Danny Rubinstein is a classic Haaretz journalist (even though he's no longer there): left-of-center but essentially a knowledgeable professional. He once wrote a biography of Yasser Arafat (he didn't manage to figure out who the man was, but not for lack of trying).
He has a very interesting article in Dissent, forwarded to me by a reader, about the state of Palestinian nationalism. His theses, in a nutshell, is that it's declining. The Palestinians are less and less interested, and in spite of Salam Fayad's efforts, a growing number are turning towards a one-state solution.
One fascinating tidbit he has dug up is that ever more of the Arabs of East Jerusalem are acquiring Israeli citizenship - perhaps 12,000 of them in the past two years.
While Rubinstein's descriptions and analysis are worth your time, his conclusions about the rise of the single-state option are less convincing to my mind. First, because Gaza is out of the equation. In spite of all the chatter about an ongoing Israeli occupation there, Israel doesn't rule Gaza, and the more time passes, the greater the number of Gazans and Israelis who will have no memory of the days it did. There's a recognized border, there's no Israeli presence in Gaza, and there's no likely scenario I can think of that will change that.
A similar dynamic is developing on the West Bank. First, there's a practical border: the fence. Much of it runs along the Green Line, and most of the rest is close nearby. Settlers can be found on both sides, and IDF troops, but a very large majority of Israelis don't cross the fence, and have written off whatever is beyond it. On the other side are Palestinians, who are effectively moving away from Israel. In the old days of the 1970s and 1980s large numbers of them worked inside Israel, spoke some Hebrew, knew Israelis, and of course they all traveled freely throughout the land. But those days are long since gone. The Palestinians beyond the fence and the Israelis behind it are becoming ever less familiar to each other, not more so.
It's true that the presence of the settlers muddies the clarity - but life is often muddy. The logic of the situation is that the present dynamics will somehow reinforce themselves, not that they'll get rolled back and keep on rolling all the way to disbandment of Israel. Sometimes muddy realities stay muddy for centuries without ever clearing up.
Finally, there's Jerusalem. The fact that the Palestinians of East Jerusalem are not enthusiastic about losing all the advantages of living in Israel in order to be part of Palestine is one of the best kept secrets in the world, though it's simple human nature. What happens, however, if significant numbers of them really do acquire Israeli citizenship: can't Israel then claim that the majority even of East Jerusalem is populated by Israelis, and thus must remain united?
If it were up to me, I'd find a way to dismantle the settlements beyond the fence, or at least the smaller and further-flung among them; I'd lope off the parts of East Jerusalem that could easily be renamed as Ramallah South; I'd encourage the uprooted settlers to move to East Jerusalem; and yes, I'd enable the remaining Jerusalem Palestinians to acquire Israeli citizenship. But, as I often say, that's just me.
