I haven't seen any comprehensive study of the PRTs. I haven't seen very much information at all, objective information, about Canada's PRT, so I think it's difficult to make a judgment on their reach, their efficiency, and how useful a tool they've been in Afghanistan.
I agree that there are a lot of different kinds of approaches. One of the principal approaches I thought with our PRT was to be a springboard to augment the Government of Afghanistan's reach within and around Kandahar and so on. It does not seem to me to have been a success, from what I've...just in the limited Canadian PRT range.
