I do not have any horse in this race, but it’s quite surprising for me that USA is jumping in and Europe and China are not championing the operations for the security in the Red See even having more vested interests on the transportation.
"Europe" doesn't have a Navy capable of projecting enough force to deal with the problem.
And, lastly, the raison d'être for today's USN is securing the free flow of global trade. So, it's very much unsurprising that USA is jumping in here (that we do not get paid for doing this service is a different matter).
That was the deal since the second world war.
