Beware the open mike. Last week Egypt's President Mohammed Morsi summoned senior politicians of all parties to discuss Ethiopia's plan to dam the main tributary of the Nile river. One proposed sending special forces to destroy the dam. Another thought buzzing the dam site with jet fighters might scare the Ethiopians off.

Ayman Nour, a former presidential candidate and a more sophisticated player, suggested that Egypt support rebel groups fighting the Ethiopian regime.

"This could yield results in the diplomatic arena," he said. None of them realized that their discussion was being broadcast live by Egyptian state television.
