"We all have been harmed. Today more than ever we need unity," said former Iranian President Ali Akbar Hashemi Rafsanjani during Friday prayers at Tehran University on July 17. It was a crucial sermon and, in the manner of many things Persian, purposefully and delicately opaque. Some thought Rafsanjani's speech was a direct threat to the Ahmadi-Khamenei regime. He demanded the release of political prisoners, an end to violence against protesters, the restoration of Iran's (intermittently) free press. Others thought Rafsanjani, speaking with the approval of the Supreme Leader, was trying to build a bridge between the opposition and the regime. For me, it brought back memories of a less opaque Friday-prayers sermon I'd actually seen Rafsanjani deliver in December 2001, in which he spoke of the need for an "Islamic bomb."
