Another great resource is this video: https://www.youtube.com/watch?v=jIS2eB-rGv0

It talks about how:

- It's much more expensive to shoot down a Shahed drone than to build one. - Iran could decide to attack water filtration plants in the Gulf countries. - It's almost impossible to win a ground invasion without spending a ton of money because of the mountains.

Basically, even if the US wins this war, the entire world economy will suffer tremendously.
