Why does Spain have sovereign territory in North Africa? That is real colonialism!
These cities have belonged to Spain since the Middle Ages and have been settled by Spaniards ever since. Well, strictly speaking, they belonged to Portugal for the first hundred years. At that time, parts of Spain were still inhabited by Muslims.
Woke governments like Spain's don't believe in borders or the rights of the ethnically indigeneous inhabitants. What happens when these beliefs hit the reality of mass invasion of military age males?
Most of them have already been sent back.
