Thank you for your comment! Those do end in "s", but are not single-name countries. My concern was that some multi-name countries' formal names end in "s", but their common/map name does not. For example, Saint Vincent and the Grenadines ends in "s", but it is more commonly known (on JetPunk) as just "Saint Vincent". The only exception I made was for The Bahamas, which does formally include "The" in its name.
