Wow...it's been a long time since I've seen a reference to Mahan in a discussion of 21st strategy. I guess what goes around, etc...
My first take on this is positive, at least in theory. In reality, we often don't have either the staying power or the high-level support to sustain civil affairs/hearts and minds campaigns in AOs that we're fighting in...much less in areas that we might fight in one day.
But I understand the need for relationship-building where the future support of the local population could be paramount.
