We essentially declared Helmand pacified in 2010, halfway through this our longest war.  Now the war's almost twice as long as it was back then and people are still being blown up by roadside bombs.  (And note that Helmand is no distant, outlying province.  It includes Kandahar and is just down the road from Kabul.)

Who are we kidding that this war will ever be won, or is actually winnable?
