It’s a descriptive statement about the law. But you’re mischaracterizing the normative principle underlying the law. It’s not based on power, but rather the moral duties incumbent on citizens.
The moral duty of a citizen is to sabotage their country when it becomes immoral.

People largely tend not to believe in this kind of jingoistic bullshit nowadays.

Is it a "moral duty" to aid your government, especially in the current social/political environment? Conscription is theoretically still allowed in the US, and you're theoretically supposed to register for the SSS, but nobody has been prosecuted for failure to do so in decades. That suggests the "moral duty" aspect has significantly weakened. Moreover if we're making comparisons to the draft, it's also worth noting the draft allows for conscientious objection. That makes your claim of "that’s not their call to make" quite questionable.
