It seems nearly every U.S. administration in recent history makes one last pitch for peace after failing to secure a lasting deal for Israelis and Palestinians. Bill Clinton held the Camp David Summit in 2000, his final year in office. George W. Bush’s “Roadmap to Peace” ended in 2008 with no final agreement. The Obama administration ended its latest serious flurry of diplomatic activity aimed at a deal last year, essentially admitting defeat. But the recent uptick in violence, characterized by gruesome stabbings, has Secretary of State John Kerry swinging back into action, holding separate meetings this week with the key players. Chances for anything other than a return to the status quo appear slim. The intractable Israeli-Palestinian conundrum may be one that the parties must solve among themselves.
