on a personal note...a few years ago my Rotator Cuff surgeon was of Vietnamese origin (outstanding work), and our long time auto mechanics are a Vietnamese family...they are perhaps the most sought after in our part of town...never even think to question their diagnoses, repair recommendations...or cost...total confidence and trust in them.
No reason the Afghanis wouldn't fit in just as well...need to do whatever it takes to get them out...even if this drags on, like the Vietnamese withdrawal did.
