Some of these truces and armistices make sense and some don't. It's true that Drakia has no real capacity for a sustained attack on the US, let alone an occupation. But the US in turn has not ability to launch offensive operations against Drakia. I get the desire for declaring victory, but do they need America's recognition to do so? As a totalitarian regime can't they completely control the internal narrative. And externally can't they simply claim that they have decapitated America and there is no functional government left to accept a surrender from? Giving any concessions requires some fear damage if the war isn't officially ended, or a conscience. We haven't been given evidence of the first and the second is completely out of character for the country that just launched a pre-emptive orbital bombardment of the world to cover up its pre-emptive biological attack which together resulted in killing over half the global population.
