Chunneling Through Gibraltar

Morocco and Spain are engaged in serious discussions of the possibility of digging a channel tunnel or "chunnel" under the Straits of Gibraltar in order to connect Morocco and Spain by 2025, according to the Washington Post. After reading of the desperation with which immigrants try to cross the Straits clandestinely by boat now, one wonders what the implications for immigration would be, but certainly it would help to draw Europe and North Africa closer.  Of course, any improvement in the Moroccan economy as a result of more developed infrastructure can only have a positive effect on the number of desperate sea crossings.
