I'm curious about the American diaspora (Americans living abroad) in the Gumboverse/Rumsfeldia universe.
1. How common was it during the economic and social upheavals of the 1970s? While leaving for Canada, Europe, Japan, South America, etc, was probably an attractive option to some, moving to another country opens up a whole other can of worms. There's all the red tape with both countries in securing the proper permits, papers, etc. Plus...money! Travel expenses, housing, cost of living...that adds up. Then again, Americans with certain job skills, college degrees, vocational/technical training, etc. may be in demand in some countries.
2. How did Rumsfeld view Americans living abroad before to his crackdown on travel (the permits required to cross into another US state, but I imagine he must have eventually ordered restrictions on foreign travel)? Did he view Americans living in other countries, for whatever reason, to be disloyal, subversive, etc? Did he wonder "why the hell would you live in [insert country here]? This country's good enough"?
3. How much of a challenge did it become to travel abroad once the s**t really hit the fan? Were there impediments like the Berlin Wall, lined with barbed wire, machine gun toting guards and landmines? Was there too much red tape to get a passport or travel tickets?
