I'm going to start with the last point first. We are extremely concerned about money being diverted to the wrong places and the wrong forces, so there is an incredible amount of scrutiny of every possible project that we consider and everything that would go up for approval.
I think that in part explains why there has not been more Canadian assistance provided to these groups. It's very difficult to find those and it's very difficult to demonstrate, because we're not on the ground and we don't have eyes and ears on the ground. It's difficult to demonstrate to yourself that you have a high degree of assurance that there's no diversion.
As to foreign fighters, there isn't a lot I can share with you other than to say it's a big concern, not just for Canada but for our allies as well. We know there are Canadians who get on planes and find their way into Syria. We know that some of them are engaged with the opposition, and some of those are engaged with the more extremist elements of the opposition. We're trying to work with our partners, intelligence agencies, and security agencies in the neighbouring countries to identify them.
