The Iran Nonproliferation Act, originally passed in 2000, is extended in 2005 to cover space-related sales to Iran and to any vendor — anywhere — that quietly supplies them. The US Treasury and State Department use the new authority to fine European and Asian space-component suppliers, sometimes long after the fact.
The European space supply chain spends a year tearing up customer lists and rewriting end-user-certificate procedures. The lesson absorbed across Europe and Asia is that American extraterritorial reach on space components is, in practice, almost unlimited — and that the only durable answer is an independent supply chain.
