In Honor of AviatorTom. . . lets have a geography quiz?

Several months ago, @AviatorTom posted some geography quizzes which were an enjoyable diversion from the usual "are-my-parts-too-big-or-too-small" questions that we see so often. So, Tom, I hope you don't mind me posting one in this category.

The letter "Z" is not common in the English language, but 15 of the current 195 recognized sovereignties have the letter "Z" in their name. Without resorting to Google. . . how many can you list? I will give you three hints:

1. Only 2 of the 15 begin with the letter "Z."

2. Of the other 13, one is mentioned in a song by Bob Dylan.

3. Three of the countries are in South America.

I'll post a complete list in an update in a few days.
