CIC's Barnett Rubin was interviewed in this Gandhara article about the demands to release Hajji Bashar Noorzai, a Taliban leader who is incarcerated in a U.S. prison.
"'He is politically important to the Nurzais in Loya Kandahar,' Rubin said of Noorzai’s status as an important tribal figure among the Nurzai, a large Pashtun tribe in the southern Afghan province of Kandahar and adjoining regions collective referred to as Greater Kandahar by Afghans. 'That is a very important constituency for the Taliban,' he added."
CIC's Barnett Rubin was interviewed by Gandhara about Taliban sanctuaries in Pakistan, which have been flagged as the "number one impediment to defeating the insurgency inside Afghanistan that now controls one-third of the country’s rural areas."
“If and only if the political agreement between the Islamic Republic of Afghanistan and the Taliban provides for demobilization and repatriation of Taliban fighters, including those in Pakistan, Pakistan will help implement the agreement and move against any who resist it,” Rubin said.
In Radio Free Europe's Gandhara, Afghanistan-Pakistan Regional Project director Barnett Rubin spoke about negotiations of a peace accord between the United States and the Taliban.
“This process provides the only existing opening to start intra-Afghan negotiations. The inter-relationships among the parts of the process are structured in such a way as to provide safeguards,” Rubin said.
