Allied leader says Afghan war effort now on track TALLINN, Estonia â€“ NATO's top official said Friday the 28-nation alliance is on track with its new strategy for winding down the war in Afghanistan next year, despite security setbacks and a continuing shortage of foreign trainers for the fledgling Afghan police and army. NATO Secretary General Anders Fogh Rasmussen offered a mostly upbeat assessment to a gathering of allied foreign ministers, including U.S. Secretary of State Hillary Rodham Clinton, who are assessing what will be required to meet the goal â€” first laid out by President Barack Obama last December â€” of transitioning to Afghan control next summer. "Increasingly this year the momentum will be ours," he said. Fogh Rasmussen asserted that the Afghan government, which has been hampered by a Taliban insurgency, political corruption, a dysfunctional economy and a dependence on foreign assistance, is starting to take more responsibility for running the country's affairs. "We are preparing to begin the process of handing over leadership, where conditions allow, back to the Afghan people," he said. "The future of this mission is clear and visible: more Afghan capability and more Afghan leadership." During Friday's meeting, which was closed to the press after Fogh Rasmussen made brief introductory remarks, Clinton was expected to press other NATO nations to provide more trainers for Afghanistan's police and military forces as part of preparations to withdraw Western troops from there by summer 2011. Fogh Rasmussen said Thursday that an additional 450 trainers are needed for Afghanistan's security forces. Insufficient numbers of foreign trainers has plagued the U.S.-led war effort for years, although the shortfall has narrowed in recent months. Friday's session also was focusing on a NATO initiative aimed at stimulating the Afghan economy by making it a priority for all foreign contingents operating in Afghanistan to hire Afghan contractors and purchase Afghan goods and services whenever possible. This "Afghan First" policy, as NATO calls it, has been deemed "the most important step in promoting the development of the Afghan private sector and supporting the economic development of the country," according to a NATO statement issued Friday. To underscore NATO's effort to coordinate all aspects of its strategy and operations with the Afghan government, Afghan Foreign Minister Zalmai Rassoul was participating in the Tallinn meeting. NATO's assessment of its exit strategy comes just five months after Obama sharply escalated troop strength in the rugged mountain nation to challenge a resurgent Taliban movement. NATO has struggled, in some cases, to coordinate military operations with Afghan civilian authorities and agencies. In a speech Thursday before the two-day NATO meeting began, Fogh Rasmussen called Afghanistan the most challenging military operation undertaken by NATO in its history. NATO was founded 61 years ago this month with the signing of a treaty of collective defense against a feared land invasion by the Soviet Union. Today, Fogh Rasmussen said, instability in places far from Europe can threaten NATO member states. "We all want to see a stable and secure Afghanistan â€” an Afghanistan that is no longer a threat to its region and to the rest of the world," he said in his speech Thursday. "We will stay in Afghanistan as long as it takes to achieve that goal. We want to continue to empower the Afghans. And gradually hand over to them greater responsibility for the security of their own country when conditions permit." During Thursday's talks, Clinton ruled out an early withdrawal of about 200 short-range U.S. nuclear weapons from bases in five European countries. She said any reductions should be tied to a negotiated nuclear pullback by Russia, which has far more of the weapons in range of European targets. No such talks are in the offing, and Moscow has shown little interest thus far in bargaining away its tactical nuclear arms. Clinton also said the Obama administration wants NATO to accept missile defense as a core mission of the alliance. The U.S. sees anti-missile systems as part of a broader effort to combat the dangers posed by nuclear, biological and chemical weapons and the rockets that can deliver them. Some European members of NATO, including Germany, have said it's time for the U.S. to withdraw its remaining Cold War-era nuclear weapons from Europe and cite Obama's pledge in Prague last year to seek a nuclear-free world. Late last year, Germany was joined by NATO members Belgium, the Netherlands, Norway and Luxembourg in requesting that the nuclear issue be put on the agenda of the Tallinn meeting. But some newer NATO members in central and eastern Europe, which lay within Moscow's orbit during the Cold War, oppose a U.S. nuclear withdrawal. They argue that the presence of the weapons is the surest guarantee of their territorial integrity. Fogh Rasmussen told reporters here that U.S. nuclear weapons play a vital defensive role in Europe and should not be removed as long as other countries possess them. "I do believe that the presence of the American nuclear weapons in Europe is an essential part of a credible deterrent," Fogh Rasmussen said.
