The Iranian missiles may have not been accurate but they were collectively bunched in the same area upon impact and more importantly, they weren't intercepted meaning US and Israeli technology failed. There were no errant missiles, intercepted or not, landing in cities because from the video footage some of those missiles came down on top of people recording from the cities.
The "delayed" Israeli retaliation says something too. I'm sure they had a retaliation plan ready beforehand. How come they haven't implemented it? To show immediacy afterwards would show Israel is undeterred. The US is worried if an F-35 gets shot down.
Overall it's also an attempt to discourage countries like China from using and developing more types of these weapons.
