In the conflict over Zionism, it seems that we have an interesting situation where both sides act as if time is on their side. This is because there is a true disagreement over what will happen if it is acknowledged that there is no longer a viable two state option.
Zionists seem to believe one of two things: one is that the US and relevant members of the world community will give their blessings at that point to a new round of full ethnic cleansing - where enough Palestinians are driven from the territories that the remainder can be incorporated into Israel without posing a demographic threat to their vision of Israel as a Jewish state.
The other possible (and more likely) belief is that it is impossible to predict confidently that further outright ethnic cleansing will be tolerated, but the moment when it is clear that it would be necessary can be put off indefinitely, and in the meantime Israel can continue to provide a Jewish state to those who want it.
Anti-Zionists seem to believe the opposite, that the world community will impose minority status on Jews of Israel as they did to the Whites of South Africa.
If anti-Zionists and those Zionists who favor delaying the recognition of the impossibility of a two state solution are right - I think they are. A solution along the lines of South Africa fits with most value systems currently held in the world far better than a solution along the lines of post-partition India - then Abbas does his people a huge disservice when he realizes that there is no longer a viable two-state solution and bends to US and Israeli pressure to refrain from saying that.
Another senior aide said Abbas was on the verge of announcing the death of the two-state solution but heavy pressure from Washington made him tone down his words.On the other hand, this is the exact type of weak betrayal of his own people that Israel and the United States orchestrated his rise to the position of Palestinian president to execute.
