It's been a huge shift, as you know, over 75 years. To talk about where we're going, we've gone from missions where we have a mandate to maintain peace, to missions where there may not be an element of peace to maintain. We're going more and more into countries where most of the national institutions have broken down and we cannot augment or necessarily rely on them to perform a mandate. Quite often we're sending troops—or the United Nations is sending troops—to places where they have to establish an institution, build it up from scratch, assist it, mentor it and then gradually transfer over.
I think that is a significantly different aspect—which requires much more nuanced training for people who are participating in the mission—from the simplistic aspect of standing there between two different warring parties and preventing them from going at it.
