This level of argumentation is so beyond sense and reason that I'm not even sure which nation you're talking about. Iran is not advancing anything and Signal is not part of the US government.
> Who is to say that the Western technocratic system of government replacing the current Iranian regime would not also be oppressive? I personally believe it would be vastly more oppressive.
Nobody is saying that because you can't but you don't have to if you want to help people out who are opressed under a dictatorship.
