The problem with all of the countries you mentioned is that their
governments are repressive and not at all inclined toward human rights.
Saudi Arabia and Pakistan are just two examples. Lots of sand in SA but no
freedom. Pakistan has an unofficial war on Americans living in Pakistan.
Geez, get caught with anything that could remotely be classified as a
missile and they'd trip all over themselves to make an example out of you.
If sand and miles of undisturbed territory is what you want, them move to
Nevada. Not only would you have all the space needed, but you'd have the
protection of the Constitution and the security provided by over 200 years
of democratic rule.
PS Those other places...great places to visit but notice, Americans never
flee the US to live there but thousands of them come from there to here.
