Israel is likely simply showing Iran that it can strike into the heart of their country if need be. I doubt the attack is meant to truly escalate anything, in the same way that Iran's attack on Israel was largely just posturing.
According U.S. news, Israel told the Americans about the small scale attack before they launched the mission.
The ball is back in Iran's court now. They either escalate, or cooler heads will prevail.
Funnily enough, it's the U.S, not Israel itself who announced that IDF is behind the strike, so we'll likely see some IDF radars and comms getting blown by Iran via Hezbollah in the coming days.
