I'm interested in knowing if they 're slavic people or are they arabs claiming to be Ukrainian or other minorities using the title of Ukrainians ?
What exactly are you asking about Arabs in this context?
I want to know if they're arabs wearing tinfoil hats calling themselves ukrainians
Nationality doesn't just apply to people born in that country. Many immigrants becomes citizens by earning their way into a country. Assuming that they're just pretending to be citizens disregards the efforts taken to become one.
