That's a very relevant question, and one that I think is posed repeatedly by President Karzai to all the interlocutors involved in Afghanistan. There have been numerous discussions, including a face-to-face meeting that our Prime Minister had with President Musharraf wherein it was expressed that Canada and other countries, including Afghanistan, had great concerns that Pakistan perhaps unwillingly was allowing this transit to go back and forth across the border, particularly in the south.
As you know, there's a mountainous region there--you're probably familiar with the terrain--that is very difficult not only to patrol, but more so to control, because of the very physically demanding nature of the terrain. The greater focus has been, of course, inside Afghanistan. But allowing for the training and the perpetration of further efforts by the Taliban inside Pakistan has been, if I could describe it this way, a shortcoming of the overall effort. The difficulty, as you can appreciate, is that it requires greater cooperation from Pakistan and its government.
