It's really not. Propaganda is very effective in non-FW countries, perhaps even more so because of lower levels of education. Cambridge Analytica had successful campaigns all over Africa and the Middle East, which had a definite effect on the outcome of elections. It can be argued that the 2016 US election result was partially influenced by this, although the tricky thing with information warfare and propaganda is that the effect is very difficult to trace back to a specific cause. It leaves the victim in a state of confusion, with no single and clear source that caused it.

Since this affects society at large, it definitely _should_ be a general concern, and not a FW-only problem.
