Acknowledging Pakistan's relationship with extremism in the past, US has said it believes that Islamabad has changed its views on terrorism.
"We have seen a shift in the Pakistani thinking. Pakistan's support for extremist elements in the past is fairly well understood, but we believe that Pakistan has changed its view and recognises that extremist elements within its borders now represent an existential threat to Pakistan itself and to the civilian government in Pakistan," State Department spokesman P J Crowley told reporters.
The next round of Strategic Dialogue with Pakistan would be held later this month, Crowley said, adding security will be a significant area of discussion.
Crowley said the shift in Pakistan's approach to terrorism is evident in the military action that Pakistan has taken within its own borders.
"Its offences in Swat, in South Waziristan – clearly, because of the flooding, Pakistan has had to take its foot off the gas, so to speak, but – and one of our messages to Pakistan is that we can’t afford to let up," he said.
"While we are helping Pakistan with dealing with the implications of the flood and the 20 million people who are displaced, we continue to encourage Pakistan to stay on the offencive," he said.
"We're seeing, obviously, in the string of attacks of the NATO convoys in Pakistan that the insurgents haven’t given up, and we want to see the government continue to take effective action. That will be our message to Pakistan when we get together in the Strategic Dialogue in a couple of weeks," he asserted.
