| The Post-World-War II-period After World War II the importance of propaganda still increased, on the commercial level as well as on a political level, in the era of the Cold War. The propaganda institutions of the different countries wanted their people to think the right way, which meant, the national way. In the USA the McCarthy-era started, a totalitarian system in struggle against communism. Cold War brought the era of spies with it, which was the perfect tool of disinformation. But the topic as a movie-genre seems still popular today, as the unchanged success of James Bond-movies show. A huge net of propaganda was built up for threatening with the nuclear bomb: pretending that the enemy was even more dangerous than the effect of such a bomb. And later, after the fall of the Iron Curtain, disinformation found other fields of work, like the wars of the 1990s showed us. |

| UKUSA In 1948 the former alliance of USA, UK, Canada, Australia an New Zealand established in World War II was formalized into the UKUSA Signals and Intelligence agreement to aim primarily together against the former USSR, although readers of the agreement say, that it is definitely only signed by the United States and Britain. A number of other countries' SIGINT agencies also participate in the UKUSA community, including those of Germany, Japan, Norway, South Korea, and Turkey. These countries are sometimes described as "Third Party" members of the agreement. In addition, some countries, such as China, host UKUSA SIGINT stations or share SIGINT on a more limited basis. |
