US has said it is difficult to resolve insurgency in Afghanistan without effective action against terrorists across the border in Pakistan.
State Department spokesman P J Crowley said during his daily news briefing that he agrees with the remarks of Afghan National Security Advisor Rangin Dadfar Spanta, in this regard.
"The National Security Advisor is right that it will be difficult to solve the insurgency in Afghanistan without effective action on the other side of the border," Crowley said in response to a question.
"As we said on Tuesday, we are seeing more effective action on the Pakistani side of the border not only because it's important to Afghanistan, but more singularly because it's important to Pakistan," he said.
"Pakistan has understood in recent months and years that the insurgents which have enjoyed safe haven within Pakistan's border now are an existential threat to Pakistan," he said.
"We've seen concerted action by Pakistan in recent months in Swat, South Waziristan and elsewhere, and our message to Pakistan is to continue on the offensive," the State Department spokesman said.
"We understand that success here involves effective action for and by Afghanistan, effective action for and by Pakistan, and likewise, effective and transparent action by India.
Through all of these processes, we will build regional security that benefits all of these countries," Crowley said.
The spokesperson said there is a historical relationship between Pakistan, some of its agencies, including the ISI, and tribes, families, entities in the tribal areas.
"We understand that. By the same token, we have long had frank, candid, direct, but respectful conversations about what we think Pakistan needs to do, not because we're telling Pakistan what to do, but because of what Pakistan needs to do for its own security interest," he said.
"We have seen what we think is a fundamental and strategic shift in Pakistan's thinking, because this insurgency has not just focused on Afghanistan.
It's turned back towards the government itself," he said.
"More of this burden is being born by the people of Pakistan. We note for a fact that probably at this point in time Pakistan itself has suffered more casualties, civilian casualties, than we in the United States suffered on 9/11," he said.
"So this is an existential threat to democracy in Pakistan. Pakistan has taken aggressive action in response.
We are still in dialogue with Pakistan about further steps. We want to see Pakistan continue to take aggressive action to deal with the elements within its borders that are a threat to Pakistan as well as other countries, including the United States," Crowley said.
