What Norway has sounds pretty crazy to me. If I am reading this correctly, Trump can disable the entire Norwegian healthcare system by calling Apple and Google and having them block BankID.

Yes, he can. Along with taxes, car registrations, banking, money transfers, rent payments, etc.

I really hope we figure something out.

I wish he would. Then the authorities would have to fix the problem.

Trump can close down a lot of the British NHS by telling AWS to stop supplying it. Everyone apart from a few countries (China, Russia, Iran, North Korea, etc.) is dependent on the US.

Yes but that’s a blunt instrument, which would risk reaction. However putting an individual on a sanctions list is routine and easy.

And a president could always just call up the CEOs and ask for their least favourite Norwegian to be cancelled without any paperwork.

As happened to ICC judges and prosecutors.
