It is a PR coup for the Coalition forces in Afghanistan and a show of "goodwill."
Pakistan has excellent surgeons who could easily perform the operation, however her subsequent post operative care would be prolonged.
This of course is being pain dor by the Pakistan government, but will take up an NHS bed and NHS staff for a very long time.
She could be flown to the U.S.......a long distance......European country perhaps, but no big coup for countries who are barely involved with the politics of Afghanistan.
tamaris has a good point............is the NHS going to take up all waifs and strays OR only the selective ones with a certain amount of PR clout?
