So, which is it? Do we forget our history and are therefor doomed to repeat it, or are we always preparing to fight the next war?

As we finish up the final chapter of our participation in Afghanistan after well over a decade, and reflect on the changes in the arch of the Muslim world from the Atlas mountains to Mindanao - what do we need to intellectually, retain for what is coming "next?"

With one eye on historical patterns and another on developing economic, demographic, and political trends - what do we need to do to man, train, and equip the armed forces best positioned to address what we think we will face, but will be flexible enough to flex to what we don't know?
