WASHINGTON - With the elimination of Osama bin Laden, Afghans have begun to worry that the US support for the war could erode at an accelerated pace now that Washingtons most wanted man is dead, according to a report in a major American newspaper. With that decade-long goal achieved, the case for troop withdrawal becomes much more convincing for Americans, The Wall Street Journal reported Tuesday from Kabul, citing Afghan officials. Americans will forget Afghanistan again, said one senior Afghan official, echoing the frequent lament that the US gave up on the region after the Soviet withdrawal in 1989. Many Afghans, according to the Journal, say the death of bin Laden in Pakistan should instead convince the US that a successful outcome in Afghanistan depends on US pressure on insurgents based in that country. President Hamid Karzai, who praised American troops for killing bin Laden, used the opportunity to reiterate his view that the locus of terrorism remains beyond Afghan borders. For years we have said that the fight against terrorism is not in Afghan villages and houses, he said. Stop bombarding Afghan villages and searching Afghan people. Secretary of State Hillary Rodham Clinton and other top US officials sought to dispel the notion that the US would lose any resolve in Afghanistan . Our message to the Taliban remains the same, but today, it may have even greater resonance, Clinton said at the State Department. You cannot wait us out. You cannot defeat us. But you can make the choice to abandon al-Qaeda and participate in a peaceful political process. President Barack Obama has already marked July of this year as the time when U.S. troops will begin to leave, starting to slowly reduce the 30,000 additional troops he sent to Afghanistan 18 months before. Even though the vast majority of the U.S. troops have been fighting the Taliban, their presence has been justified in large part by al-Qaedas continued survival. With July 2011 around corner it now easier to argue that the fight against al-Qaeda and whatever is left of it should focus on Pakistan, and it is time to end the war in Afghanistan, said Vali Nasr, a professor at the Fletcher School of Tufts University and until recently a senior adviser on Afghanistan and Pakistan for the State Department.
