Act stupid? Shoot, I don't even have to act. It just comes naturally!
The Office of Strategic Services (OSS) was the predecessor to the Central Intelligence Agency. In 1944, it published a sabotage manual that was distributed to resistance forces in Nazi-occupied Europe. It covered a lot more than just making bombs and blowing up bridges. In fact, it's a practical guide to success in any large organization--or at least how to have fun.
The manual shows how you, the ordinary person, can disrupt society at the micro level in order to ultimately degrade the effectiveness of Nazi Germany's empire.
I'm beginning to suspect that I've already seen the influence of this manual at past employers. It's like an anti-leadership guide.
You can see some choice selections of the book at Messy Nessy Chic or the full text here.
But . . . what foreign power is trying to disrupt us? How did they get so many agents into positions of authority?
