What country borders Morocco?
It depends on whether you consider Western Sahara as being part
of Morocco.
If you do, (as does the Moroccan Government), then Morocco's
neighbors are Algeria, Spain (Ceuta and Melilla), and
Mauritania.
If you do not, (the position of the African Union and the United
Nations), then Morocco's neighbors are Algeria, Spain (Ceuta and
Melilla), and Western Sahara.
