If you did want to stop CNC machines being used in Iran or North Korea, why not just use the GPS chip to disable the machines if they're inside those countries?

I don't see what's to be gained by causing the machines to fail if they've been moved to the other end of a factory.

No GPS inside of a metal box (like a shipping container). You can also spoof GPS since it's a one-way passive signal.

Maybe they'd put the machines in facilities with bad GPS reception?
