It's very important to differentiate between cultures and nations on the one side and the regimes on the other, because the regimes always like to claim that they represent those nations, which they have no claim to, for obvious reasons. It's not about curtailing broadcasting in the Russian language or in Farsi or whatever, because that's what they will try to pretend: that this is an attack on the language and culture.
No, it's very important to draw the line clearly: Cultures, languages and the diversity of this country—the beauty and richness of this country—will always be welcome, but for those malicious attempts by these regimes to hide behind the cultures and languages to enact channels of propaganda and misinformation, those will be prevented in the most effective and strictest way possible.
