WASHINGTON  - The military-to-military relationship between the United States and Pakistan are on the road to recovery, said top Pentagon official General Martin Dempsey.

Asserting that he was encouraged by the meeting, the chairman of the US military’s Joint Chiefs of Staff, said there may be bumps in the road, and hoped that some key issues between the two countries could be resolved before the Nato summit in Chicago in May.

Dempsey said he has seen the ‘CliffsNotes’ version of the meeting between the US Central Command commander, Marine Corps General James Mattis; the commander of Nato’s International Security Assistance Force, Marine Corps General John Allen; and Pakistani Army chief General Ashfaq Parvez Kayani in Islamabad on Wednesday.

“There will be some things both of us want to resolve before the Nato summit in May. One of these issues is the opening of ground lines of communication through Pakistan to Afghanistan,” Dempsey told reporters. The closure of the supply route, Dempsey said, according to American Forces Press Service, has affected not only the US, but also the other countries helping Afghanistan. Reopening of the supply routes, will help solve the problem the coalition faces as it begins withdrawing troops and equipment, Dempsey said.

Martin Dempsey didn't say whether any agreements emerged from talks among the two nations' top commanders in Islamabad.

Dempsey said the start of the warm weather fighting season in Afghanistan and the planned withdrawal this year of 23,000 US troops, along with equipment, added to the urgency of reaching a deal to reopen overland supply routes through Pakistan.

“I am not an advocate of breaking contact with military-to-military relationships that we’ve taken decades to establish,” the chairman said. “We lost about 10 years of contact with our Pakistani military counterparts – they weren’t coming to our schools, they didn’t train with us, there weren’t any exercises, no military sales program, no technology transfer, no security cooperation.”

This isolated the Pakistani military from the US, and it created a gap between the nations’ militaries. “I do believe there is a difference in the world view of the generation of Pakistan’s leaders who are more or less my peers, and the next generation,” he said. “That is having an effect.”

One program the US military put in place to combat this is a vigorous liaison program. For example, at US Central Command there are 64 different liaison officers working at the command, many of them from Pakistan.

“That program, plus our school exchanges is beginning to rebuild all that, but it doesn’t happen overnight,” Dempsey said.
