I agree that I think the US is at capacity, especially with Ukraine turning into a quagmired war of attrition, and anything left going to Isn'treal there just is not enough around to support the facade of the paper tiger.

I also have heard some military guys talking, and how the US is operationaly, its clear they are resting on the idea no one will attack the us so they dont need to be fully ready at all times

But when the DPRK strikes I expect it to be long and drawn out, containing communism is still a key goal of the US

Exactly, the big problem the US has is that once it runs through the existing stockpiles of ammunition it can't produce new ones at the rate they're being consumed. For example, from 2008 to present, Lockheed Martin was able to produce 800 missiles, around 50 a year. https://armyrecognition.com/news/army-news/2023/lockheed-martin-announces-delivery-of-800th-thaad-interceptor-missile-system

To counter the 180 missiles Iran reportedly launched, requiring up to 2 interceptors each, would have exhausted nearly HALF of all THAAD missiles ever produced. And that's assuming there are enough launchers to even fire that many interceptors at once. The US is completely unprepared for the scale of war it is provoking around the globe.

Or they pretend to be tumbling oafs to create situations where they have to "regretfully" personally intervene, leading to maximum destruction around the world. The US will propably disintegrate soon after, but the territory of the former US will still be best off, resulting to a sucessor state having the best base for hegemony.

In short: The US nuclear doctrine.
