Source? Newsweek - BTW. I don't see anything on Russian media (I checked RT and TASS, and even the Amsterdam-based Moscow Times (not pro-Russian)- and Russians are usually very open about talking about their military exercises to the Russian, and international readers.

Newsweek is supposed to be a center - slightly left-leaning - mag (rag). https://www.allsides.com/news-source/newsweek#what-this-rating-means

Their source for the claim that Russians are having nation-wide Nuclear attack drills? "I dunno, I made it up" + general rundown i.e. Russia Bad, Putin a madman with lotsa links to 'prove' the general part.

Can we say PROPAGANDA by author Ellie Cook [coughs - Hack] yet?
