CHICAGO: In Middle East politics, peace is made not between friends but between enemies, suggesting the harshest foes have a better chance to achieve peace than those who claim to be friends. That pattern has shaped some of the region’s most consequential breakthroughs, from the 1979 Egypt-Israel peace treaty to the 1993 Oslo accords and Jordan’s 1994 peace agreement with Israel. Each was incomplete, each left the core Palestinian question unresolved, but they all reflected the same hard truth: progress has usually come only when adversaries were willing to sit down across the table.
