I have noticed a trend recently that is exemplified by the article from YNET http://www.ynetnews.com/articles/0,7340,L-3707501,00.html. Arab leaders are now calling for a two state solution, while OPPOSING one of them being a Jewish state. Rather than calling for a single Palestinian state, Arab leaders advocating for the Palestinian side are PRETENDING to be supporters of "two states for two peoples" by agreeing to "two states." However, their intent is that BOTH states will become Palestinian states. They drop the "for two peoples" part of the statement. This is to be accomplished by insisting on the Right of Return of Palestinians to what is now Israel. As the Palestinians would then only be slightly less than a majority and have a much higher birthrate than the Jewish population, in a manner of short period of time, Israel will end up with a Palestinian majority. Thus, BOTH states would become Palestinian dominated states.
The statements by Abbas are strong indications that he is NOT as moderate as many on the world stage would like him to be. The only difference between his position and Hamas' position is that Hamas is unwilling to wait to eliminate the Jewish state through the Right of Return.
The biggest problem that those desiring peace now face is that Israel seems to have a choice between maintaining a single state in which Jews dominate Palestinians, many of whom live in occupied territories, or agreeing to peace terms under which there will not be a Jewish state into the future. Even the political left is beginning to see this problem. The issue is not simply a question of a one or two state solution, but of "two states FOR TWO PEOPLES" meaning that one of those states would be a Jewish state. Even Ahmadinejad supports Abbas' version of two states in which in essence both would become Palestinian in short order.
Simply put, what is going on now is that leaders who seek the elimination of Israel as a Jewish state are SUPPORTING a TWO state solution, only doing so in such a way that ultimately NEITHER of those states will be Jewish. Their support for "two states" allows them to APPEAR to be moderate, when they are very much not and continue to seek the end of the Jewish state.
They really want two states for one people.
