A mild annoyance within Ukrainian politics. But in reality, bearing no connection to the problem that Putin makes it out to be. A bogeyman basically.

Per the Wikipedia definition:

The bogeyman (/ˈboʊɡimæn/; also spelled or known as bogyman, bogy, bogey, and, in North American English, also boogeyman)[1] is a mythical creature used by adults to frighten children into good behaviour.
