Benin

Most people haven't heard of Benin but that really isn't their fault - in 1972, Benin came under the control of a communist regime and the CIA retaliated by secretly removing the country from every single world map they could get their hands on. Most admit that it was kind of a petty gesture and probably not really worth it in the end. As they say, once you go communist, you never go back until you realize that communism is basically just a terrible time and not any fun at all. Benin democratized in 1991, but CIA budget cuts during the late eighties mean that most globes still label it as "New Liberia."

Benin shares borders with both Niger and Nigeria, which must be awfully confusing.
