A flag officer is expected to be ready for duty and able to ascertain when she cannot perform that duty. Lopez would definitely be courtmartialed and definitely be punished, perhaps severely. Whether or not Steele should have understood her psychological position, her rank demands that she obey the orders of her superiors, and explicitly defying or implicitly 'reinterpreting' those orders is a failure that can't go without recrimination.
Historians might well put some of the blame on Steele - certainly the Fedayeen strategy was predicated on understanding Steele's blindness in this regard - but the GTVA military justice system probably won't. GTVA flag officers are expected to be able to make extraordinary and decisive sacrifices if orders demand.
