From the Pentagon's perspective, they're probably meeting that with either AWS or Azure. They probably look at self-sufficiency as a national, not organizational thing. So long as the thing is built and located in the US and owned and operated by Americans, it means they're not giving up any self-sufficiency.

Certainly. But until we reign in the military as a portion of government spending, big military investments should have direct civilian benefits not civilian costs. https://en.wikipedia.org/wiki/Military_Keynesianism (note the "Keynesianism" is somewhat tongue-in-cheek) does not cut it for the latter.
