Reference to the Ursula K book, around these parts it's been memed that people here cause the future to happen by controlling the lathe of heaven. The sound effect part is just brrrrrrrr.

In this case, it's being mixed with the Assad meme which is the "who must go" meme or "assad curse", everyone that ever says Assad must go has been outlived by Assad's rule. In short, Netanyahu saying this about Assad is like latheing his own end.

Lathe of heaven, it is essentially about someone who can alter reality with their thoughts.

We joke about how the worst possible ideas get manifested, as if plucked straight out of the air the moment we speak of it.

The Lathe of Heaven - movie

https://en.wikipedia.org/wiki/The_Lathe_of_Heaven_(film) IMDB

George Orr, a man whose dreams can change waking reality, tries to suppress this unpredictable gift with drugs. Dr. Haber, an assigned psychiatrist, discovers the gift to be real and hypnotically induces Mr. Orr to change reality for the benefit of mankind

with bizarre and frightening results.

The device where the shrink manipulates these dreams to try to remake reality is kind of like a Monkey's Paw of unintended consequences. Such as trying to fix racism and everyone in the world having grey skin.
