I think we have to consider these days that we're increasingly talking about the issue of the foreign fighter problem. I think we understand they constitute an increasing theat to our country. There is evidence that while they don't engage in a significant number of acts when they come back to their countries of origin, the acts that they do engage in are increasingly problematic in levels of seriousness.
I also think what has been lost in some of the discussion of the foreign fighter issue is that by allowing these foreign fighters to go overseas, we're continuing to supply these groups, ISIS. At least in some instances, they appear to be increasingly dependent on foreign fighters to maintain their operations and their tactics. I'm focusing on one particular issue, but I think we need to be cognizant of CSIS' ability from both perspectives. It's not simply a matter of their coming back here, which is problematic, but we're providing a pipeline for these groups, and we probably need to consider very closely stemming that flow.
