We tend to think of spies getting caught when we think about brain washing. The idea was to control the spy, change what they believed and turn them against their own country. The enemy in war is often demonised by governments and the media. They use brainwashing techniques to describe the ‘enemy’ calling them the ‘reds’ or the ‘yellow peril’ or worse. They portray the enemy as inhuman. The reality is quite different, so the spy is confused when he’s caught.
