Did Iran Suffer a Nuclear Setback?

UANI Advisory Board Member ray Takeyh writes: "It appears that a huge explosion occurred at the plant, specifically at a warehouse used to construct advanced centrifuges. Iran had hoped to roll out a large number of such machines to boost its uranium enrichment capacity. The U.S. press has speculated that Israel was responsible. In the past few months, there have been various accidents at Iran’s military facilities, including at a missile production factory. Amid widespread speculation of sabotage, Iranian leaders have not confirmed the cause of the explosion, but they say it will likely lead to delays in developing advanced centrifuges."
