The country is pretty amazing, they have cut the poverty rate in half each year for the last couple of years and there are mom and pop markets every where. Plus, they run a trade surplus and have really rebuilt their infrastructure. They are in much better shape than Mexico.
Laos is a basket case, a really shabby little hole. Cambodia shows great promise though. All the countries do have some of the best people on earth though, I would gladly live over there.
BTW, I ran into dozens of vets that were going back to Nam to see it, every single one remarked about how well they were treated, and none of them regretted their trip.
One thing for sure: Burma is the worst out of all these countries.
