WASHINGTON (AFP) - Top US officials Sunday delivered a sharp warning to Afghan leaders to resolve the election crisis, saying it would be irresponsible to send in more US troops unless a strong government is in place. I think it would be irresponsible and ... it would be reckless to make a decision on US troop level if, in fact, you havent done a thorough analysis of whether in fact theres an Afghan partner ready to fill that space, top White House advisor, chief of staff, Rahm Emanuel told CNN television. Two months after Afghanistans August 20 presidential elections, the count has been bogged down by allegations of widespread fraud and ballot-box stuffing mostly in favour of President Hamid Karzai. Karzai, a key US ally who has led his country since December 2001, is said by preliminary results to have won about 55 percent of the vote. But amid the fraud accusations, he has come under mounting pressure to accept a run-off against his rival ex-FM Abdullah Abdullah, reported to have garnered about 28 percent of the vote. The electoral stalemate is complicating a major US policy review ordered by US President Barack Obama on the way forward in Afghanistan, with the number of US troops already set to reach 68,000 by the end of the year. The White House is mulling a request by top US and NATO commander on the ground, General Stanley McChrystal, to commit extra 40,000 troops to Afghanistan to step up counter-insurgency operations. We would love the luxury of this debate to be reduced down to just one question, additional troops, 40,000. This is a much more complex decision, chief of staff Emanuel insisted on CNN. Before you commit troops, which is not irreversible, but puts you down a certain path, before you make that decision, theres a set of questions that have to have answers that have never been asked, Emanuel argued. And its clear that after eight years of war, thats basically starting from the beginning. And those questions never got asked.
