Propaganda: Propaganda is communication that is primarily used to influence an audience and further an agenda which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented. - from Wikipedia
Question: How can you determine when an individual is under the influence of propaganda?
Answer: When they stop looking for the truths that either or both sides of a conflict use as the foundation of their propaganda.
>Putin’s propaganda is WILDLY effective.
I'd argue so is the United States, much more so than Putin's. If you compare the evils committed by the US to Putin's, Putin cannot hold a candle to the US. The difference is that Putin bears that burden across multiple decades, while the US changes figure heads every 4-8 years, and with that washes away the stains of the country into the haze of time.
With all that being said, I am not pro-Putin nor pro-US regarding this conflict, and I agree with the article that the best course is for the United States to admit defeat, (and additionally, not in the article) stop expanding eastward (through NATO), and to keep their promise to Russia (which was to stop expanding NATO).
Edit: I'd like to add, the seed of Putin's "fascist/nazi" claim is that in 2014, Ukraine's new government eliminated minority rights (i.e. the Russian minority, which represents less than half of the population). And, the US started funding the neo-Nazi faction (Azov battalion) of the Ukrainian army. A quick duckduckgo search will pull up articles for both of these claims.
