Here's my basic assessment of Palestinian-Israeli diplomacy, written in 1990:
there can be either an Israel or a Palestine, but not both. To think that two states can stably and peacefully coexist in the small territory between the Jordan River and the Mediterranean Sea is to be either naïve or duplicitous. If the last seventy years teach anything, it is that there can be only one state west of the Jordan River. Therefore, to those who ask why the Palestinians must be deprived of a state, the answer is simple: grant them one and you set in motion a chain of events that will lead either to its extinction or the extinction of Israel.
Such matters as borders, water, armaments, the status of Jerusalem, Jewish communities in the West Bank and Gaza, so-called Palestinian refugees—in brief, the central issues of the Oslo period—cannot productively be discussed as long as one party still aims to murder the other. In principle, something along the lines of the Oslo agreement could turn out to be workable—but only after the Palestinians definitively and unequivocally, and over an extended period of time, demonstrate that they have made their peace with the existence of the state of Israel as an irreversible fact.
