Afghanistan conflict: Ghani queries troop exit deadline Afghan President Ashraf Ghani says America's two-year deadline for pulling out the last of its troops may need to be "re-examined". US President Barack Obama is committed to withdrawing all US soldiers by the end of 2016, as Afghanistan looks after its own security. But Taliban militants stepped up attacks dramatically last year and have declared victory over the US. Mr Ghani told US broadcaster CBS that "deadlines should not be dogmas". Disagreements over the timetable for the US-led coalition's withdrawal dogged Mr Obama's relations with the new Afghan president's predecessor, Hamid Karzai. BBC
