Inside America's powerful Israel lobby

At the annual policy conference of the American Israel Public Affairs Committee this week in Washington, a conservative Christian couple from eastern Tennessee told me that their son had decided to join the Israeli army. It was one of many surreal moments during the three-day gathering hosted by AIPAC, the lobbying group devoted to ensuring close U.S.-Israel ties that remains extraordinarily influential in Washington. "We just love God, and we just love Israel," the couple beamed, when I asked why they had come to the conference.

Amid an energized and at times almost circuslike atmosphere, just about everyone in attendance shared two main preoccupations: the 2008 U.S. presidential election and confronting Iran. And this year's conference saw record attendance: more than 6,000 people, coming from every state in the country and exceeding last year's crowd of around 5,000. Many of them were American Jews, of course, but the evangelical Christian community also made a strong showing. For those feeling apocalyptic about the turmoil in the Middle East, pastor John Hagee was there to greet them.
