But the UN DHR doesn’t seem to have been written as law. It was written as a declaration, in line with our own Declaration of Independence. It lists our ideals that need to be spelled into law. That lets it be airy and vague in a way laws cannot.
It isn’t “every law.” It’s not written to be directly operationalised. You’re comparing a declaration of values to operational law; they’re words in different ways and contexts.
> Is a "declaration of values" more than words if there is no power that is willing to enforce it?
Yes. Nobody directly enforces the policy papers or the Declaration of Independence. That doesn’t mean they don’t have corporeal value. In part, due to being translated into laws.
