Really? “Tons?” Exactly how many? Permanent residents, not temporary.
Wiki: “Vatican City (is a walled enclave within the city of Rome. With an area of approximately 44 hectares (110 acres), and a population of 842, it is the smallest internationally recognized independent state in the world by both area and population.”
I will take Pope Vladimir seriously when the Vatican lets in a couple hundred random, unscreened Muslim men, aged 18-30, like they are asking the rest of Europe to accept.
Permanent residents, no screening.
I don’t know what their status is, but apparently quite a lot of Muslims.
