I remembered another topic that requires re-mentioning in case it matters. It's very Grroomer God-ie, but important.
If you ever wish to trust another nation based on one group of sociological study actions, pick How They Treat Their Family. It's a good core subject to analyze civilians as the true core of a nation. The civilians show the true heart of the nation. Therefore, study families to see if a country is worthy of business, respect, and if necessary for a Groomer God with a Punisher quality... who to kill off like a plague.
