Ah hell, you make one deeply drunken joke and suddenly you’re at -25…
FWIW, the US does have a whole host of laws and various treaty clauses that dictate US citzens cant be held to account by a foreign power without either US government consent or consent of the party. Our extradition and criminal parity treaties mean that, in criminal cases, we might let a citizen be tried outside of the US, but calling a US citizen is really really difficult to pull off. Thats what I was referring to when I said “we fought a war”. The UK government cannot compel him to testify, by hundred-year-old-treaty, without US consent.
But calling a US citizen to testify in front of a foreign legislative power is 100%, by both treaty and hegemony, entirely consensual on the part of the called party. Musk can just say no, and there’s nothing that can be done without getting the buy-off from the state dpt, which… we’re an oligopoly, we’re not going to hand over a billionare.
HOWEVER the UK is entirely able to hold his business interests and investments ransom, which would be highly effective. If parliment is serious about this they’ll do that, but since I have no more faith in the UK government than my own (okay a little more, the US is in a bad place, the tories would honestly be a step up in most states) I absolutely do not expect them to go after musk in a way that even slightly might work. Which I would love to be proven wrong about, please, some government hold this asshole to account.
