A toppled nuclear plant spilling radioactive goo?
If I'm correct, that's a political and I'd offer it is incomplete.

Propaganda is a form of communication aimed towards influencing the attitude of a population toward some cause or position.
Propaganda is information that is not impartial and used primarily to influence an audience and further an agenda, often by presenting facts selectively (perhaps lying by omission) to encourage a particular synthesis, or using loadedmessages to produce an emotional rather than a rational response to the information presented.
While the term propaganda has acquired a strongly negative connotation by association with its most manipulative and jingoistic examples, propaganda in its original sense was neutral and could refer to uses that were generally positive, such as public health recommendations, signs encouraging citizens to participate in a census or election, or messages encouraging persons to report crimes to law enforcement.
