Additionally the rivalry between the US and China is off topic I'm not talking about that.
My statement is, Asia is superior to the US in terms of Manufacturing/infrastructure. I can add more to that as well. In terms of ICs, Asia also dominates. The US is behind Asia on all three of these fronts. As a general statement this is still true. You didn't invalidate anything with your off topic comment here.
That being said, the united states is the dominant spender in terms of defense. They are number one on this front and in terms of technology. I don't think the world has ever seen a military industrial complex as massive and as advanced as the one the US has built. What you say here is true and it's major. It's not included in "manufacturing" but it's intimately connected and thus worth mentioning.
So in essence if there is a place that will convert to majority nuclear power it's most likely going to be Asia that still has the capability to do this. I don't think it's likely for the US.
