But how many countries are there? How many just in Africa, and how many in Europe, Asia, Latin America..... and how can anyone recognize all the papers from each individual country. If they took all the royalty from all the countries and mixed them up with thousands of other people from over the world --- could you really pick them out? The Crown prince of Uganda? Or his sister the princess? (if they exist) or the Crown prince of Thailand? Or of Belgium? I could probably recognize Prince Charles of England but not his siblings if I came face to face with them --- but I'm not even sure about that.
Wow.. Is that the excuse you used when you failed geography??
(whine) "but there's too many countries!..." (sniffle)
If the screeners can't cut the mustard, get out and find a job at McDonalds..
