The classified documents, which SPIEGEL has seen, demonstrate how systematically the Americans target other countries and institutions like the EU, the International Atomic Energy Agency (IAEA) in Vienna and the UN. They show how the NSA infiltrated the Europeans’ internal computer network between New York and Washington, used US embassies abroad to intercept communications and eavesdropped on video conferences of UN diplomats. The surveillance is intensive and well-organized – and it has little or nothing to do with counter-terrorism.
