It’s worth remembering that America has the toughest system of intelligence supervision in the world—way tougher than France, tougher than Germany. No one else has this combination of a court with judges who are not appointed by the government, who are appointed by the Supreme Court. You have congressional scrutiny—and it may well be that Congress is in different hands from the party that holds the White House—plus you have executive power in the White House. And then you have a very strong professional code within the NSA. What we have seen from the Nixon experience was this: when Nixon tried to politicise the CIA, trying to overrule it, trying to politicise the FBI, it ended in disaster. And I think that although the American record over the last 50 years certainly has some black spots, I would far rather live under the American system of intelligence oversight than I would under the French. So I think we should all learn from the American system and try and copy it.
