Cheap missiles, #drones and uncrewed vessels are making sea denial accessible to states and non-state actors. Naval power can defeat attacks but cannot guarantee commercial confidence. Freedom now depends on resilient routes and markets: Jonathan D. Caverley & José Alberto González Aranda or-f.org/40599 #MaritimeSecurity

What happens to global trade when its most critical sea lanes are blocked at once? From a 76% plunge in vessel traffic through the Strait of Hormuz to drone and missile threats in the #RedSea shipping is shifting from efficiency to survival.

Thanks @tshugart3 for engaging with my argument. For me, the below is the key point, though I also don't think any amount of dispersion makes a FIC posture survivable or wise for the United States. In part, this i because of how I define U.S. interests. But, it is also a difference between U.S. in how we see the lessons of the war in Iran and the limits of what more dispersion can accomplish.
Replying to @tshugart3
So underlying this is not really an argument that a SIC posture can perform the same denial mission better. It's an argument for abandoning much of that mission, then designing a smaller force for the narrower set of commitments that remain.

E.g. how come S Korea sustains a navy ~twice as big from an economy ~half the size (while also fielding a huge land army)? Ditto a Japanese economy of ~about the same size? Why can the smaller French/Italian economies sustain slightly bigger fleets* with much better availability?

I have an article on the US Govt’s latest salvo in its (erstwhile?) allies’ direction in the @spectator this week… BLUF: it’s true that the Western ‘middle powers’ are a disparate bunch. But the more the US coerces them, the more it incentivises them to align away.

I personally believe it would have made an enormous difference, as I argued in the piece below. Ukraine needed modern weapons to better match Russia’s capabilities, especially at the start of the war, before China, North Korea and Iran got involved. reader.foreignaffairs.com/20…
🇺🇸🇺🇦 Biden Admin alums like Jake Sullivan continue to argue that giving more weapons, more quickly, such as ATACMS, wouldn't have made a difference. A talking point debunked by General Cavoli. Panetta is correct and Sullivan is wrong, unsurprisingly.

Sounds familiar
A way i’ve seen charterers get around jones act recently is by discharging & reloading in the Bahamas mid route I’ve seen this happen with vessels loading in the US Gulf, stopping in Freeport, then going to the East/West Coast At $90k+/day people will find alternative solutions

Jonathan Caverley (@jcaverley) uses a "kill chain" model to compare the potential effect of Chinese military capabilities, with and without Taiwan, on the contested zone where U.S. and allied forces would operate. tnsr.org/2025/06/so-what-rea…

We were lucky enough to have our YouGov/The Economist poll in field when the US bombed Iranian nuclear facilities. You can see the partisan realignment in real time
