There was no actual plan that could have been made short of one that spanned multiple administrations over at least a decade to spin up enough missile or interceptor manufacturing for such a thing.

It’s just silly to think that the US has the domestic manufacturing base left to do such a thing short of generational scale timelines. The line workers you need in those plants are in grade school today. Better start introducing machine shop again!

Trump could have decided day one of his admin he wanted to do this, told everyone, and held off until the last day of his presidency to fire the first shot. At best you’d get a couple more weeks of ammo.

It’s a pure fantasy to think US arms manufacturers - even given a blank check and nationalized - could get a supply chain going in under a few years. We do not even have the semi-skilled manufacturing talent to spin up such a base, much less the latent capabilities to easily pivot.

Sure there is no plan. Having one would not have helped much either. You can’t plan your way out of having spent three generations outsourcing your industrial base.

The WWII comparisons are laughable. Today the US would still be getting factories on-line by the same time the atomic bombs were dropped. We would have a whole cycle just learning how to build things again - much less actually build them.

To build ammo at a “all out war” scale you would need entirely different weaponry designed foremost to be rapidly built. You cannot rapidly scale up manufacturing of current designs. If we could, we already would have since there is effectively an unlimited decade out backlog of demand for just Patriot missiles and has been for close to half a decade already. The common rebuttal that a factory would need 30 years of increased demand to make the investment worthwhile proves the point.
