Reacting to Snowden’s allegations, US figures, like former CIA and NSA Director Michael Hayden, made no reference at all to America’s obligations under international law, to its interest in protecting diplomacy, or even to the unfairness and bad faith involved in spying on partners with whom one is supposedly negotiating in a transparent way. Nor did Hayden suggest any national-security concern that might justify spying on the EU (there is none).
