He did remove their supreme court’s ability to try him for his crimes, his party is the majority in Israeli parliament, he’s disbanded the war cabinet, and they’re actively trying to push back the next election date. So yeah, pretty much a dictator.

So arguably, a puppet dictator is more accurate. Although the way they interact would lead one to believe Bibi is the actual puppet master.
