Comment: May they all accomplish the mission and return home.  Speaking of the specific mission to "kill terrorists", what war was ever fought without the primary mission to destroy the enemy? Certainly no war was ever fought with the prime objective simply to spend time in conflict.  Finally, if you are victorious you have created a power vacuum and how can you avoid "nation building"?  Killing terrorists is a  tactical objective.  Doing that in partnership with indigenous forces and denying sanctuary to the enemy are operational objectives.  Now I  want to hear a clearly defined strategic objective for expending more blood and treasure.
