Nuclear weapons aren’t ships. It’s a categorical difference that matters a lot.
You can double check if you want but pretty sure U.S./E.U. adversaries like China and Russia already do flybys and have ships sail close via international waters. It’s good for a quick media hit in western countries but nobody who is serious or matters really cares about it. The U.S. does this all the time - called freedom of navigation exercises. The Chinese or Iranians will saber rattle a bit for no good reason other than strengthening their crappy, despotic regimes, but nothing comes of it.
Re China: I think you’re wrong, largely. First, China as a whole should be wealthier. It has 4x the population. It should have 2x-3x the GDP of the U.S. yet it doesn’t. Interesting.
Second, building empty skyscrapers is a hallmark of collapsing nation states of planned economies. It’s motion for the sake of motion. It’s like a broken window fallacy.
The U.S. has some very interesting advantages and certainly doesn’t need nuclear weapons to win “the war”. It’s winning it right now as China faces a population catastrophe and the U.S. continues chugging along like always.
Again, Chyna (Trumps terms) fear is overrated. Not sure what people/Trumpists are so worried about.
> Why spend a lot more on ships now when everything points to you being both richer, more technologically advanced and with better industrial capacity in 30 years than the US?
Not sure any projections are really convincing here. And the U.S. isn’t even trying as a unified country and is spending massive amounts of money wastefully (Iraq/Afghanistan, etc.).
