US is the largest oil producer as of last year, they're on the way to being net exporter, they mostly import and finish Canadian oil. US is energy secure as of last year, which is why they've been so emboldened in ME. I do agree that cyber attacks and other costly blowback is on the horizon. This is certainly extremely troubling development.
E: Sorry account seems to be rate-limited?
US net exported crude and other petroleum in September and is projected to be sustained net exporter in the next year. I'm not suggesting they are completely inoculated against global energy market shift, but they have nominal guaranteed energy security because USNavy can protect all those transit routes. Whereas China, Japan, Korea, most of Europe with limited blue water projection capabilities would struggle very hard to maintain ME oil access if Iran decides to start tanker wars in the Hormuz.
