when they are talking amongst themselves or to Arabic media, and what they are saying is that the state they seek from the U.N. is just the first step in the destruction of Israel, as stated by Fatah Central Committee Member Abbas Zaki (h/t Israel Matzav)(emphasis mine):

The settlement should be based upon the borders of June 4, 1967. When we say that the settlement should be based upon these borders, President [Abbas]understands, we understand, and everybody knows that the greater goal cannot be accomplished in one go.

If Israel withdraws from Jerusalem, evacuates the 650,000 settlers, and dismantles the wall – what will become of Israel? It will come to an end…

If we say that we want to wipe Israel out… C’mon, it’s too difficult. It’s not [acceptable] policy to say so. Don’t say these things to the world. Keep it to yourself.
