Pakistans ambassador to the United States has urged the Obama Administration to enhance his countrys counterterrorism capacity and asked critics of Islamabads anti-terror policy not to blow militant threat out of proportions. There is a difference, you need to be alarmed and concerned but you need not feel as if Pakistan or Islamabad is about to fall tomorrow. I think there has to be a sense of realism, Ambassador Husain Haqqani told USA Today. Questioned about reports of Taliban advances in the wake of Swat peace arrangement, Haqqani said Islamabad is very much conscious of the challenges facing it and with a strong central government and a large military it can stave off any militant threat.
