"Yes," Jones replied. "Despite massive work on the part of the administration at the civilian, at the military level, there still seems to be that reluctance to engage comprehensively and buy-in to an overall plan that, I think, would really help Pakistan in the long-term."
Six U.S. servicemembers were killed in Afghanistan during an operation in Kunar province, near the border with Pakistan this week. Thirty-four American servicememebers were killed in Afghanistan in the month of March.
With Yemen's president Ali Abdullah Saleh facing increasing pressure to step down, Jones echoed language coming from the White House, noting that the situation in Yemen is "very worrisome."
"Saleh's been very skillful over the years in being able to consolidate and maintain his power. The trends Yemen are not good, this could be a major problem and where terror is concerned, this would be a safehaven that would be a very troubling turn of events of us," he said.
Amanpour asked if the U.S. should try to keep Saleh, who has been an ally of the United States in the fight against terrorism, in power.
"There are certain things that we can do and that we can't do," he said. "When events reach a certain stage, they have a life of their own. It would be nice to be able to think that we could do everything and make the world perfect the way we want it," Jones explained, "but that's not the case."
