Iran is in the headlines, so what's on your shelves? (Or in your Kindle). I've read these: 

The Persian (2025, 4.2 on Goodreads) by David McCloskey: Written by a former CIA analyst, this recent release opens with a surprise strike on Iran and follows a CIA officer and an Iranian official attempting to prevent a regional collapse. 

Protect and Defend (2007, 4.4) by Vince Flynn: Part of the Mitch Rapp series. After a strike on an Iranian nuclear facility, the U.S. faces a retaliatory plot from a Hezbollah mastermind. Capture or Kill is also supposedly good (haven't read it tho.)

The Tehran Initiative (2011, 4.4) by Joel C. Rosenberg: A political thriller focusing on a CIA operative working to stop an Iranian nuclear threat before a full-scale U.S./Israeli military intervention becomes inevitable. 

The Island (2021, 4.7) by Ben Coes: Features a massive Iranian-led attack on Manhattan and the United Nations. It includes a U.S. retaliatory strike on the Iranian Presidential Palace in Tehran.

And for getting inspiration on a topic (like Iran) I always go to BookDNA first ... much better than Goodreads because it is curated.

Oh, and of course I should give my own a plug - have you read GOLAN (4-5 on Goodreads)?

GOLAN, This is the Future of War, asks a question few want to consider. What will happen if Iran acquires nuclear weapons in the next ten years? In true Future of War style, GOLAN explores the question through the eyes of front line participants on all sides, in a conflict set ten years into the future. Featuring military tech that is on the drawing boards today and characters you won’t easily forget, GOLAN throws the reader straight into the center of a nuclear storm and doesn’t ease up.
