WASHINGTON - The United States on Monday stood by plans to halve the number of its troops in Afghanistan this year and reduce them further in 2016 following Afghan President Ashraf Ghani's suggestion that President Barack Obama review his deadline.But Ghani's comment adds to a growing debate over whether the White House will stick to its plans, already amended twice, of cutting US troops to about 5,000 by the end of this year and drawing down to a "normal" US embassy presence in Kabul at the end of 2016.Ghani may have also given political cover to Obama should the president decide he needs to renege on his withdrawal pledge to preserve shaky gains made over 13 years of war and to avoid a collapse of local forces that Iraq witnessed last year."My guess is that he probably will re-evaluate these decisions in due course," said James Dobbins, who was Obama's special representative for Afghanistan and Pakistan until July.Among the factors at play are the course of the war itself; reconciliation efforts between the government and Taliban; US public opinion and the 2016 US presidential debate.If Obama decides to change course, he may find a more receptive domestic audience.American skepticism about the Afghanistan war seems to be moderating in the face of the rise of Islamic State fighters who have seized swathes of Iraqi and Syrian territory following the US withdrawal from Iraq in 2011.According to a Washington Post-ABC poll published on Monday, support for the war in Afghanistan has risen since 2013. A 56 percent majority says it has not been worth fighting, but 38 percent said the war was worth the costs, up 10 percentage points from the record low in July 2013.
