In the NewsBy Sydney J. Freedberg Jr., AOL DEFENSEPersonal Military Ties Key to Successful AlliancesWASHINGTON - Just back from his trip to Asia, the jet-lagged Chairman of the Joint Chiefs of Staff attended graduation ceremonies at the Pentagon’s National Defense University, where he singled out NDU’s first-ever Vietnamese graduate, a colonel in the People’s Army of Vietnam, as an example of the kind of relationship-building the US military must do around the world and especially in the Pacific. “Practicing the science of human relationships,” said Gen. Martin Dempsey, “is crucial to the survival of civilization.” In his prepared remarks, Dempsey held up last year’s intervention in Libya by a coalition of 18 nations as “an object lesson in the value of military-to-military relationships” “There were certainly some bumps in the road,” he said, “but there’s no way an operation of that magnitude could have been planned and executed that quickly – and just to be clear, we’re talking about hours and days, not weeks and months – without military relationships based on trust.” “As senior leaders,” he told the NDU graduates – drawn from the US military, civilian agencies, and abroad – “you will find it increasingly important to practice the science of human relationships. As you become involved in making

strategy, you will need to nurture relationships to make that strategy work.” The US military has spent decades working with foreign countries, from exchanging liaison officers and advisors to conducting international exercises to fighting side by- side in war zones from Korea to Afghanistan, but, said Dempsey, “my trip to the Asia- Pacific showed me we have to do even more.” On a more mundane level, relationship-building is central to the administration’s strategic guidance released in January. The new strategy scales down America’s massive military presence overseas – not only in the war zones of Afghanistan and Iraq, but also in Europe -- in favor of what it calls “innovative, low-cost, and small-footprint approaches to achieve our security objectives, relying on exercises, rotational presence, and advisory capabilities.” Dempsey has previously emphasized the Defense Department’s human capital, not high-cost hardware, as what will get it through an era of tight budgets. And while the chairman oversees all four military services, it’s his own service, the Army, which has most enthusiastically embraced the building-partners mission both in its budget and in a recent strategic workshop at the Army War College.

terrorist network. Panetta repeatedly emphasized U.S. Frustration with attackers crossing the border from Pakistan. It is essential that Pakistan stop “allowing terrorists to use their country as a safety net in order to conduct their attacks on our forces,” he said alongside Afghan Defense Minister Abdul Rahim Wardak. “We have made that very clear time and time again and we will continue to do that, but as I said, we are reaching the limits of our patience,” Panetta said. The United States clearly wants Pakistan to take on the Haqqanis before the bulk of U.S. troops have left the region by the end of 2014. In Washington, Gen. Martin Dempsey, chairman of the Joint Chiefs of

Staff, told a Pentagon news conference that the United States needs to continue working with Pakistan, despite frustrations. “It’s our view that those Haqqani, notably, the Haqqani network, is as big a threat to Pakistan as it is to Afghanistan and to us, but we haven’t been able to find common ground on that point. So that’s been very frustrating,” he said. He added that the United States is “extraordinarily dissatisfied with the effect that Pakistan has had on the Haqqanis,” but also mindful that Pakistan has taken on other insurgent groups at great cost to its own troops. Panetta’s remarks capped a week of some of the boldest language and actions by the administration against its stated ally. Just a day before, he stood in the capital of Pakistan’s arch rival, India, and declared that drone

strikes against terror suspects would continue, dismissing Pakistan’s claims of sovereignty by noting that U.S. sovereignty was jeopardized by terrorists as well. A senior U.S. Official acknowledged Thursday that the recent increase in drone strikes on insurgents in Pakistan - targeting mostly al-Qaeda but other militants as well – is partly a result of frustration with Islamabad. The official spoke on condition of anonymity to discuss sensitive operations. And earlier this week, NATO sealed agreements to ship tons of supplies out of Afghanistan through northern and western countries, bypassing Pakistan, which has kept its borders closed to NATO trucks in response to the killing of 24 Pakistani troops by NATO forces.
