I take very strong exception to this comment. There are many, many soldiers today (and in the past) conducting FID extremely effectively who have not gone native. In fact for FID to be effective you cannot go native or you will lose your perspective and be unable to accomplish the mission for the United States.
It seems to me that we need people like Gant to do real foreign internal defense. But do we have a military that can live with its officers "going native"? If not, can we really do FID?
