This article deals with the question of determining a future Israeli-P
alestinian border within the context of an originally developed analyt
ical framework. Following the presentation of a previous model (Tagil
et al., 1977, 1984), the authors offer a greatly modified and more det
ailed framework for the analysis of border determination. The modified
framework emphasizes factors such as national ethos and two alternati
ve national 'imperatives' (territorial and ethnic) as important determ
inants of borders. The article then applies the model to the Israeli c
ase, offering detailed historical and statistical data related to the
determination of a future Israeli-Palestinian border. The article demo
nstrates the dramatic transformation (among Israel's elites and public
alike) from a territorial to ethnic imperative and from integration (
annexation of the West Bank and Gaza) to separation (Israeli withdrawa
l from the territories). In offering a general model for studying inte
rstate and intercommunal conflict, and in demonstrating its applicabil
ity to the Israeli-Palestinian conflict, this article is of immediate
relevance to numerous other ethnic disputes around the world. The arti
cle, originally submitted three months prior to the Israeli-Palestinia
n mutual recognition of September 1993, has assumed particular importa
nce by identifying the parameters that may determine the future border
s in the Middle East.
