Imagine if Hezbollah gets their hands on this?
Yes, that’s what Israel no doubt fears the most. Russia has armed Iran, it’s ally, and Iran arms Hezbollah with anything it can. It’s risky. No doubt that’s why Israel released this information to put pressure on Russia to secure these missiles and not transfer them. Their use in an asymetrical war is dubious to begin with. They’re more about messaging NATO and other nations that Putin wants to intimidate, including Israel.
