"This commitment is very costly to Britain in terms of money and more importantly in terms of human lives," he added.
"The high level of British casualties is something which brings trauma to Britain, but we know that it is very strongly in our national interests that... (Afghanistan) doesn't become an incubator again for terrorists."
Mr Miliband said Britain had not been asked to send more troops following the US surge, but kept the number "under review".
So: costly in human lives; British troops and British casualties; and fighting (if I may be excused so tactlessly aggressive a term) so that Afghanistan 'doesn't become an incubator again for terrorists'. I'm declaring it FKATWOT 12. (For the origins of this mellifluous expression, see here and follow the links.)
