WASHINGTON - A leading US lawmaker Sunday rejected the claims that the pull out of CIA's station chief from Pakistan was a 'major setback and called for an end to heaping blame on Islamabad for the development. "No, I don't believe it will be a major setback, and I think we need to stop having public debates about whether Pakistan is at fault for or not at fault for, and whether we're not at fault for or at fault for," said Senator John Kerry, chairman of the Senate Foreign Relations Committee. "That does not help this process," he said in an interview with Christiane Amnanpour on ABC's programme 'This Week. "Pakistan, it's a very fragile democracy that has emerged out of eight years, nine years or whatever, of the (Pervez) Musharraf dictatorship. There are huge economic difficulties facing them, huge internal difficulties facing them," Kerry said."They've (Pakistanis) made many decisions that, in fact, put themselves at risk in many ways. The drones are very unpopular all through Pakistan. And yet they're allowing us...," he added. Kerry said no one a year ago would have thought that the Pakistanis would have 147,000 troops in the north western parts of the country. "Nobody would have thought they would have gone into Swat and gone after the insurgents or South Waziristan. Their soldiers have a two-year tour. Their army has been somewhat stretched. And I've spent hours with their chief of command, General (Ashfaq) Kayani. I believe they know exactly what they want, what we want them to do, what they have to do, and I believe at some point it's going to happen." Kerry and Senator Richard Lugar, the ranking Republican on the Senate Foreign Relations Committee, mourned the death of Richard Holbrooke, President Barack Obama's point man on Afghanistan and Pakistan. Lugar said, Holbrooke was trying to get the money into Pakistan that John (Kerry) and I had fostered in so-called the Kerry-Lugar bill. Now, the Pakistanis liked the idea of a five-year programme. They liked the idea of money for schools and legal enforcement and the rest of it. But getting it there, who -- who runs it? How can you monitor it? This took all the diplomatic skills of Richard, and he still wasn't quite there with it. But in answer to the question about Pakistan, all we can do, we are trying very hard diplomatically, a five-year programme, because it is critical."
