Afghan President Ashraf Ghani said in an interview broadcast on Sunday that the United States might want to "re-examine" the timetable for removing the remaining U.S.-led coalition troops in the country by the end of 2016.

"Deadlines concentrate the mind. But deadlines should not be dogmas," Ghani told the CBS program "60 Minutes" when asked about the issue.

"If both parties, or, in this case, multiple partners, have done their best to achieve the objectives and progress is very real, then there should be willingness to re-examine a deadline," added Ghani, who was elected last year.
