It is difficult to answer that question.
If the conditions are such that the Canadian Forces are no longer of value, I think it would be indicated by a number of things: the Iraqi government itself, our allies and coalition partners, and most importantly to me, the wishes of the Government of Canada. I continue to monitor the operation, the region and the reasons we're there.
At some point in the future I would look forward to being able to provide the advice that Iraq has come far enough and Daesh has gone backwards enough that we don't need the military forces there anymore. We're not at that point right now. In an environment and in a region that's affected by so many variables, I couldn't possibly point to where military forces are not required internationally or where, as a subset of that, the Canadian Armed Forces would not be required. It would be pure speculation.
