Professor Sir David Omand was the first UK Security and Intelligence Coordinator, and formerly director of GCHQ. Spending much of his career leading the UK\u2019s national counter-terrorism strategy, he was directly responsible to the prime minister for homeland security. His book \u2018How Spies Think: 10 Lessons in Intelligence\u2019 is described as a \u201ccall to arms for more rational decision-making\u201d and shares the spooks\u2019 problem-solving skills. In this in-depth interview, Sir David argues the government has \u201cfailed to protect its citizens\u201d against Covid-19 - after several warnings that a global pandemic was likely - and warns we now have \u201cyears of great disturbance\u201d ahead; blames \u201cdisinformation, conspiracy theorists and social giants\u201d for encouraging division and \u201ccreating a fundamentally fragmented society;\u201d and recalls the pressure of making judgements then delivering difficult news to the PM - including giving the order to \u201cready the fleet\u201d after warning Margaret Thatcher that Argentina was about to invade the Falkland Islands, and his ringside seat whilst Tony Blair dealt with 9/11 and the invasion of Iraq.\xa0
