> i.e. intentionally creating a state of terror

That's not really a good description of terrorism. Terrorism is going after non-military targets, or at least indiscriminate targeting, for the express purpose of causing terror.

If an enemy tank platoon is rolling down the street, the operator of an antitank missile certainly knows that blowing up the lead tank and killing the crew in front of their compatriots is going to instill terror in the rest of the tank platoon. Taking that action anyway is correctly described as an act that intentionally instills terror, but that's not an act of terrorism. War, regardless of if it's waged lawfully, is often terrifying.

The way to successfully argue that Israel's pager attack was an act of terror is to show indiscriminate targeting - not merely highlight how terrifying it is to have a bunch of high level officers killed at once. However, investing a lot in the latest information gathering technology sound like the opposite of indiscriminate targeting.

I obviously can't speak for how the public writ large would react to our hypothetical. But I can at least speak for myself that if Hezbollah somehow, say, flew a bunch of drones onto IDF bases and killed officers, then that would be an act of war but not an act of terrorism no matter how terrified it might make Israelis feel.
