How to analyze an obvious lie

"Jews Are Being Ordered to Register in Russian-Controlled Ukraine"

How would a rational, thinking person react to such a story?  Is there any conceivable reason for Russians to be acting this way, any possible benefit to them, especially considering that they know it will immediately be used against them by the usual propagandists?  Isn't it much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much, much. much, much, much . . . more likely that this is either:

1. a false-flag instance of anti-Semitism created by the enemies of Putin and Russia intended as part of the huge anti-Russian propaganda campaign going on now; or
2. an outright lie by the consistently lying presstitutes?

This isn't even slightly difficult.  Registering Jews?  They can't even be bothered to be creative.
