With the situation in Afghanistan worsening, the Obama administration has drawn up a detailed plan for ending the US combat mission in Afghanistan by 2014, The New York Times reported Monday. The phased four-year plan, which the U.S. will present at a NATO summit in Lisbon this week, also calls for handing over security duties to Afghan forces over the next 18 to 24 months, the newspaper said, citing American officials. The report came in the wake of Afghan President Hamid Karzai's warning that the US military had to scale back operations and reduce intrusiveness into Afghan life or risk fueling the Taliban insurgency. Karzai's comments, which appeared to be in conflict with the US military's counter-insurgency strategy, were met with dismay from US lawmakers. They also put Karzai squarely at odds with US and NATO commander General David Petraeus. Senator Lindsey Graham, who met with Karzai this week as part of a congressional delegation, said he was "just stunned" by the president's remarks. "We were briefed by our military commanders that the night raids... are making a huge impact on the Taliban, the insurgency as a whole," he told ABC television's "This Week." "We talked about, quite frankly, looking long term with Afghanistan about having two air bases in a permanent fashion in Afghanistan to provide stability, so at the end of the day, there was no discussion about a difference between Petraeus and Karzai, in terms of strategy," Graham added. Karzai said "the time has come to reduce military operations," a statement that runs counter to the US plan of intensifying military operations against the Taliban ahead of the start of a planned US military withdrawal in mid-2011. He urged the US military to lighten its footprint in his country and shift toward a more civilian operation to "reduce the intrusiveness into the daily Afghan life." In many respects, according to the Times, the US exit plan follows the precedent set in Iraq, where a similar troop surge and strategy shift under President George W. Bush in 2007 enabled American-led coalition forces to eventually hand over security duties to the Iraqis region by region. By last summer, Obama was able to pull out two-thirds of United States forces from Iraq and declare Americas combat mission there over. Iraq is a pretty decent blueprint for how to transition in Afghanistan, an unnamed American official was quoted as saying. But the key will be constructing an Afghan force that is truly capable of taking the lead. The new transition planning comes as prospects for last years troop increase in Afghanistan and reformulated strategy there remain uncertain, according to the paper. American forces in Afghanistan have tripled under Mr. Obama, and Gen. David Petraeus, the commander, has claimed that they are making progress. But the last of the reinforcements arrived only recently, and officials in Washington have said it is too early to say whether the strategy will work. Officials emphasized Sunday that any transition would be based on local conditions, not a dictate from Washington, and would be a process, not an event. This will be ground-up, one official said. The American government is already assessing which areas could be safely handed over to Afghan security forces and will be ready to identify them late this year or early next year, officials said. Every few months, more areas will begin the transition, with the last at the end of 2012. Those will almost certainly include the toughest areas, like Khost in the east and Kandahar in the south.
