Ceuta is located on the north African coast and shares a border with Morocco, an Arabic-speaking country with a population of 36 million. But the case offers an important example of why advocates of open borders refuse to confront the more difficult geopolitical questions that surround immigration. The de facto government of the cities would become that of local militias composed of ethnic Moroccans—probably with financial and military support from the Moroccan state. None of this has actually happened, of course, because neither Spain nor its exclaves have open borders. Were such countries to actually open their borders, countries like Lithuania would cease to exist as independent entities almost immediately.
