Afghanistan and Pakistan: on the battle for Kandahar - Myra MacDonald, Reuters.
In the vast swirl of debate about Afghanistan and Pakistan, it is worth taking the time to read this piece in the Small Wars Journal by Michael Yon about the looming battle for Kandahar and the central importance of the Arghandab River Valley (pdf document).
Just as "a tiger doesn't need to completely understand the jungle to survive, navigate, and then dominate", Yon argues, you don't have to master the full geographical and historical complexity of the Afghan war to grasp the importance of the Arghandab River Valley in securing Kandahar - a battle he suggests will be crucial in 2010.
