Talking smack without any basis to follow through. The reality is that the USA controls the seas. They are the only one that is able to prevent or allow sea traffic. And the current administration is willing to use that power.
I’m not sure that’s true anymore in a world of supersonic missiles and drone swarms. We haven’t seen a carrier group tested yet because of the risk the US would escalate to nuclear but it’s not clear we can defend them against these new weapons.
