If the caliphate is defeated, it will be far from an end to the problems.  As the article rightly points out, the point of  military intervention is to force a political solution. The West has failed miserably in both Iraq and Afghanistan, and it could be argued that those conflicts are what led to the rise of Islamic terror.  And these aren't the only failures -- Viet Nam was a disaster which gave rise to the Khmer Rouge in Cambodia, and even WWII's triumph was tainted by the rise of the Iron Curtain.

Canada would do well to offer humanitarian aid and peacekeeping services rather than send troops.  We may wish to consider diplomatic efforts to try to broker peace between the warring factions as well.  I cannot agree with sending troops since we need not defend Canadians in these conflicts and violence generally begets more violence.
