The point is, that’s not what happened. Crimea had never been turned on for Starlink because, get this, it was Russian controlled and the US had international sanctions against providing communications services there. So a day or so before Ukraine was about to launch an offensive there, Elon gets a call from Ukraine to turn on Starlink for that area. Legally, he cannot due to the sanctions. As he told the All In summit, if the U.S. Govt told him to, he would have turned it on, but no call came from the US Govt. By doing nothing, he was both following US law, and NOT cowboying into international military policy.
Which is the exact opposite of what Issacson wrote. Issacson has since clarified that he got it wrong In the book.
Anyways, SpaceX is in the middle of provisioning Starshield for the US military, and that will be the appropriate service for such things going forward, all under US military control.
