I mean the long and short of it is we have no idea. We think the interceptors are running out. Movements of THAAD batteries from South Korea to West Asia seem to imply that. B52s strapped with cruise missiles are replacing a lot of Tomahawk strikes, which again implies they're running out of those missiles. It seems Iran launches fewer drones and missiles, but more get through, again implying lack of interceptors. But we really don't know what their stockpiles are, the fog of war is thick.
As for manufacturing, it's functionally impossible to scale up manufacturing in the United States in a way that would make any difference for this current war. It is possible that they do so after, realising it is a fool's errand to fight China without having any real weapons manufacturing base, especially when they depleted their stockpiles in this farcical "special military operation," but that would require rejecting the God of Short Term Profit. Unlikely that the current rulers of the USAmerican Empire would make such a choice.
Thr long term effects of this is worldwide rearmament. Users like @xiaohongshu@hexbear.net have been predicting this for a long while, and I think after this war it's even more likely. Countries within the empire are seeing the United States cannot protect them. They do not have the arms nor the will to do so. The obvious answer is you need to develop your own arms industry, your own defensive platforms, your own missiles, etc. The empire is always gonna prioritise Israel (look at Ukraine rn, or the Gulf, both of which, despite being more "important," are getting no arms).
