So here's a little puzzle I thought up yesterday — which sets of currently existing countries or dependencies share the same last five letters (but do not share the entire last word)? (Yes, that's an imperfect proxy for rhyming, but that's the question.) So Uruguay / Paraguay and Armenia / Slovenia don't quite work, since they only share the last four letters. Likewise, North Korea / South Korea don't work, since they share the entire last word. If we weren't limited to currently existing countries, or could also use other geographical areas, we could have Syria / Assyria, Russia / Prussia, Liberia / Siberia / Iberia, Saudi Arabia / Bessarabia, and many more.
But what are the sets of country names that fit my criteria? The names must (1) refer to countries or dependencies that now exist, (2) be the standard English-language names for a country or a dependency (an example of the latter would be Guam or Gibraltar — let's use the CIA Factbook as the official reference), (3) share the last five letters, and (4) not share the last word. Also, if you want to make it extra sporting, (5) do this from memory rather than by consulting a map or other printed or electronic resource (except perhaps to check the things you've come up with from memory).
