A smart move on Iran's part would be to _respond_ to anything by anybody with strikes specifically on Israel.  Most of the rest of the civilized world would cheer every strike since Israel is so hated due to their Gaza genocide and other things.  Even the U.S. at the street level since more and more people are waking up and becoming resentful that Israel controls the U.S..

The idea would be to keep the enemy on alert and under strain for an extended period of time.  Hopefully this will ultimately lead to depletion of resources, the collapse of political leaderships, and economic collapse.

Once Israel-targeted responses became the norm for the U.S., 'collective West', and associated Israel-controlled gulf states to expect missiles to target semi-random things in Israel, they would let down their guards making effective strikes against them more practical.

One of the main reasons that the U.S. attacked was that they need an excuse for their own upcoming economic collapse.  They hope to blame it on high energy prices caused by Iran.  Ergo, it is best for Iran to avoid becoming a scapegoat by blanket targeting of energy.  At least for now.
