Iran's Nukes in Rabbit Warren of Tunnels, Bunkers Hidden arsenal complicates nuclear standoff By Emily Rauhala, Newser User Posted Jan 6, 2010 7:44 AM CST 3 comments Comments Mahmoud Ahmadinejad, center, helped found the Iranian Tunneling Association and now keeps his country's nuclear program buried underground. (AP Photo/ISNA, Amir Pourmand) (Newser) – Iran is using a network of tunnels and bunkers to shield its atomic complex, obscuring the size of its arsenal and complicating calls for military action against the rogue state. Military experts from the United States and Israel say a well-hidden nuclear program is especially hard to take down. "It becomes literally a black hole," an ex-CIA analyst tells the New York Times. "You can’t be sure what’s taking place.” Behind the target-busting tunnels is a familiar face: Mahmoud Ahmadinejad. The president started his career as a transportation engineer and went on to found the Iranian Tunneling Association. His camp says the country's atom-splitting ambitions are purely peaceful. Critics, including Defense Secretary Robert Gates, question the need to keep a peaceful program buried deep underground.
