I slightly disagree

It is a big change for Iran to launch from their own land. It certainly is a move to appease their hardliners while also giving the biggest heads up to Israel that missiles and drones were on their way. It seems to be done to save face, while limited the need for Israel to have a severe response.

But, if Iran really wanted to do something they would unleash Hezbollah who have enough rockets to overwhelm the iron dome. This is not the best Iran can do. They are capable of much more. But, It’s what they are most willing to do at this time, IMO.

This is all a big game and Iran is just slightly escalating within the unwritten rules. Hopefully Israel continues with a mostly measured response and just hits back at some mostly useless Iranian military targets or even none Iranian land targets.
