Morally justified
 
"The war in Afghanistan was a morally justified response to the attacks of 9/11."
 
"And its goals — of ending Afghanistan’s status as a rogue terrorist state, while building democratic, pluralistic Afghan institutions in a Western image — were noble. But in practice, the challenge proved too great."
 
"The Americans and their allies, including us, did their best. There is no shame in this stalemate. Now it is up to the Afghans."
