Afghanistan: Mission accomplished is a 'dangerous' phrase

UK troops can come home from Afghanistan knowing it was mission accomplished, Prime Minister David Cameron has said.

He met forces stationed at Camp Bastion in Helmand, a year before the last British combat forces are due to leave Afghanistan.

Mr Cameron, who ate breakfast with troops, said they could "come home with their heads held high''.

Professor Michael Clarke of the Royal United Services Institute said while British army personnel had done ''a pretty good job'' talk of a mission accomplished was politically ''very dangerous''.

''Whether Afghanistan will succeed after 12 years of involvement is something that we really can't do very much about, and that's not really a strategic success,'' he said.
