wishing death on the people of NATO (not just memes/quips about dismantling the organisation)

That is not what the phrase "Death to NATO" means, setting aside that "NATO" doesn't have a "people" as it is a treaty organization, unless you mean, like, the heads-of-state and such who run it, vote in it, etc. In that case, phrasing it as "people of NATO" is the most pseudo-populist thing I have heard in years.
