The dollar being the reserve currency is international finance. Nothing to do with the superiority of one navy over another.

What? The Houthis shutting down a major global shipping route and the US openly giving up on restoring it is not "regional politics."

Navies appear to be obsolete (edit: I'll exempt ballistic missile subs from this statement, though.) You don't even need a navy of your own to sink another country's navy these days.

When $100M in armaments can take out a $10000M carrier, it's time to rethink things.
