"Our most likely estimate is that replacement costs are approximately $91 billion. Military and strategic assets — nuclear facilities, missile and drone production infrastructure, air bases, naval vessels, and air defense systems — make up roughly half that total, at approximately $46 billion, which is equivalent to 4-6 years of Iran’s pre-war defense budget"

How exactly did they arrive at this estimate? I would like to see a building-by-building breakdown, or at least a methodology. Feels very vibe-researched tbh.

You could get to a pretty good figure by assuming the Iranians know they can ask for at least twice as much. Three times as much isn't even pushing it.
