I don't know about that. She essentially promised them an entirely new market with an enduring legacy of expansion. In return, all she asked was that they quit enabling the war effort, something they are uniquely suited to do. By reducing war profiteer revenue by say...10%, she is allowing them to expand their entire business empire by 25% into an area where they are assured zero competition.

The mystery is how she would enforce this. Little do they know that she really doesn't care. Her and the hero's long term goal is to make the human lands self-sustaining and raise the overall standard of living, no longer reliant on the war.

I idly wonder what her plans are for the demon realm as well. We're not even aware of what long-term issues it has been having.
