FILE - In this Tuesday, Sept. 13, 2011 file photo, Field Marshal Mohamed Hussein Tantawi, head of Egypt's ruling military council, points to a painting as he accompanies a visiting delegation at the defence ministry in Cairo, Egypt. Egypt's ruling military has inserted a new element of confusion even as Egypt tries to sort out turmoil surrounding its upcoming presidential elections. The generals now insist a new constitution be written before a new president is seated, a rushed timeframe that some fear may prolong their hold on power. (AP Photo/Amr Nabil, File)

The tea party has changed, but it's very much alive. (AP Photo/Eric Gay)

Ilijaz Pilav speaks during an interview with Reuters in his office in Sarajevo March 23, 2012. Twenty years ago this Friday, April 6, 2012, the West recognised the Yugoslav republic as independent and Serb gunmen fired on peace demonstrators in Sarajevo, the opening salvo of a siege on the capital that would last for 43 months. Eleven days after April 6, 1992, men in uniform turned up at Pilav's clinic in the eastern town of Srebrenica. Pilav would escape from Srebrenica on foot through a forest on a summer day in 1995, hours before it was captured by Serb forces, who went on to massacre 8,000 Muslim men and boys there and bulldoze the bodies into pits. Seventeen of Pilav's relatives were among the victims. It is in their memory, Pilav says, that he is now fighting in court to force Bosnia to rewrite a constitution that paid for peace by enshrining ethnic segregation into law. Picture taken March 23.
