> The US have the capability to generate bombs indefinitely.

The same US which had to re-build and re-open factories to be able to support Ukraine, and had an important shortage of shells for some time?

The same US talking with their allies to build ships for them?

US generals said that their defensive munition is not infinite. Middle Eastern countries said that they have Patriot stockpiles for 4 days.

We're past WWII. Nobody has that capacity anymore. Some of the tech and factories built these gigantic battle cruisers are not present anymore even.

US may, and can pulverize Iran if they want, but it'll be much more expensive than WWII era, because of how interconnected the world is now, and this is how post-WWII world has been designated. Make everyone depend on everyone, and make war very expensive as a result.
