Puneet Talwar has been confirmed by the US Senate to a key diplomatic position, becoming the second Indian-American to join the state department. Talwar, who was a key aide of President Barack Obama on the Middle East, would now serve as the assistant secretary of state for political-military affairs. He was confirmed on thursday by voice vote. In September last year Obama nominated Talwar, who played a key role on negotiations with Iran, to this top diplomatic position in the state department. After being sworn-in, Talwar would be the second Indian-American serving as assistant secretary in the state department after Nisha Desai Biswal, who is the assistant secretary of state for South and Central Asia.
