Krepinevich's actual quote from the linked blog entry is:
Therefore, Krepinvech suggests, we should reduce "the military’s continuing relatively high emphasis on conventional operations... in order to support language and cultural training, as well as other 'soft' skills that are particularly useful in irregular warfare."
Anyone who's familiar with his commentary on Vietnam should expect this. I don't think he's calling for a total scrap of HIC training, but rather articulating (possibly badly) the need to keep other forms of training in place or expand them to deal with what we are most likely to face.

Again...too many (on both sides of the debate) seem to want to frame this as an "either/or" when it really has to be a "both."
