I have a question, and I don't think it's been answered anywhere.
But at what point do ships lose value? I mean, don't we assume that Russia and China have the technology to 1) find our massive ships/carriers/whatever they're called, and 2) have the missile capability to destroy them without driving a boat up next to them? Or they would have that technology by the time any conflict between us would likely exist (if they don't already?).
So in my uneducated eyes, you have two main classes: your naval assets you use for routine patrols, forward basing, and power shows, and second, your "strategic" assets - mainly your stealth subs.
Anyway, I think that's an important distinction to make. Although the entire argument is still stupid and merely political.
