What impact will the pandemic have on human security and human rights? I put that question to Sir Alex Younger, who until September headed MI6, Britain’s Secret Intelligence Service. From an undisclosed location, he spoke of a technological race threatening the security and economic strength of liberal democracies. But 30 years in espionage, he said, convinced him of the power of human agency: “We created the things that divide us, and it’s in our power to solve them.” Did you grow up wanting to be a spy?
