I think we have to be frank about the security situation in southern Afghanistan. It has changed over time. In 2006, at the time of Operation Medusa, you had set-piece fights with the Taliban; that has changed to a more asymmetric form of attack, which is quite insidious. Its whole effort is to undermine civilian confidence, to make NGOs wary of doing work there, to really strike at what we're trying to do.
We have a challenge in terms of meeting that. I think the Canadian Forces is coming up with some very effective means of addressing it, but it's a challenge that remains. I think that is probably the number one issue, trying to address that security situation so that we can work effectively and deliver what we need to deliver to people in southern Afghanistan.
