Looks like I'm right. I don't read in German regretfully, but what I get with machine translation fully supports my point - national discretion allows for civilian or humanitarian aid rather than an automatic military response
Moving the goalpost out to "automatic military response" is not compelling.
The relevant quote in the document is actually in English though.
So it does say required by all that is in their power. Whether that is enforceable is another measure, but that is true for a lot of rights.
