I just picked up AoD a few days ago after many, many years of playing HOI2. I've been playing a '36 Germany campaign and have a question about intelligence missions. I'm just fooling around trying to learn how everything works so I did smear campaign against France even though the odds weren't good. Now it keeps continuing without end. Every so often I get a message that my mission failed and one of my spies dies. After several months I have almost no spies in France and can't figure out how to turn the mission off. What do I need to do?
