> The US has protected global sea lanes for 80 years.

But rather than protect global sea lanes, the US is bombing Iran. That’s not the same thing.

The idea that the war isn’t costing money for personnel because those people would be doing something anyway makes no sense. They could be doing something else. In fact, they could be doing something that increases the wealth and wellbeing of the world, rather than destroying things. So from that perspective, the cost is far higher than what is shown here.

Then there’s the loss of innocent lives. It would be unconscionable to put a price tag on the lives of dozens of Iranian girls killed when their school was flattened and to show it on this website, and yet, this is not “free” either.

The strait of hormuz is the opposite of protected right now. Insurance companies aren't willing to cover ships if they enter the strait to pick up a load of oil, so little commercial traffic is occurring.

The real cost should include the spike in oil prices, the world consumes about 100 million barrels a day, so every $10 increase costs the world a $1 billion a day. We're already up ~$10, and it might continue to rise depending on how things go. You probably should include LNG in there too. If this oil halt is protracted, your stocks and bonds will be dragged down as well.

We have surplus carriers specifically to allow them to average a large percentage of their time at home unlike container ships who spend the vast majority of their time in service. Many systems that are both bespoke and complex means lots and lots of maintenance issues.

Sure the Navy can Airlift in parts etc, but that’s obviously very expensive and less obviously more dangerous.

They haven't exactly been sending aircraft carriers after pirates. It's a huge excess of firepower for any traditional threat to shipping.

The US has liked to portray itself as the world's protector, but often that's just spin. The carriers are big weapons of war, meant for waging war.

Exactly: that protection isn't happening right now because those resources are doing something else. The money would be spent anyway, but doing something that is normally considered useful, and that useful thing is not happening to the same capacity as before. Therefore there is an opportunity cost to consider.

They aren't all deployed at all times and the Ford is more than overdue to be in Port. The sailors are notably suffering on this deployment and there is a ton of deferred maintenance.
