If the United States has explicit proof of Osama Bin Laden’s presence in Pakistan’s border regions, then it will categorically pursue him, US Deputy Secretary of State John Negroponte has said. Speaking to Charlie Rose, he said that as far as Bin Laden was concerned, the US would pursue him regardless of any permission from Pakistan to conduct a military operation within its borders. “I’m pretty confident that that’s the way the president would react,” he added.Negroponte said that Pakistan was a very important country with respect to its proximity to Afghanistan. On President Pervez Musharraf’s continued importance to the country, he said that it appeared that the prime minister’s role was taking on greater importance.
