CHICAGO — Time is not on the side of peacemakers in the Middle East. Even relentless optimists are giving up. The Israeli-Palestinian conflict has become increasingly overshadowed and orchestrated on both sides by extreme and uncompromising religious groups that view their political mandate as holy and sacred.

This is hindering any peaceful resolution in the short run and will prove increasingly prohibitive to a political settlement in the long run. More than ever, peace is an unattainable mirage.

During the last 25 years, various competing stakeholders in the region have embraced religion as the dominant paradigm in determining their domestic policies. In many Arab countries, the fundamentalist revival is as significant as it is disconcerting. Hezbollah has emerged in Lebanon as a potent force, Iraq has been transformed from one of the Middle East's most secular countries into a theocratic-militant state, and Hamas is now surging in Palestine and diluting the authority of President Mahmoud Abbas.
