France officially rejects the idea of French ethnic nationalism. France’s nationalism is civic and linguistic - the French nation is defined in terms of citizenship and language, not in terms of ethnic ancestry - in fact, the French government does not even know the ethnic/racial composition of their country, since they refuse to collect statistics on it. So I disagree with the suggestion that France is an “ethnostate”
> Saudi Arabia is named after the Arabs
Both the Saudi royal family and the Saudi religious establishment have always opposed Arab nationalism; the only significant Arab nationalist force in Saudi politics was the outlawed Arab Socialist Action Party opposition, which was mostly crushed by the Saudi regime in the 1980s, and by 1991 or so was extinct.
