To understand how and why past decisions were taken it is essential to look at them from the inside out, not with hindsight. To comprehend the decision-making process, it helps to study specific choices, such as those:
to commit British troops to the Korean War, 1950;
to reverse the Egyptian nationalization of the Suez Canal, 1956;
to apply for British membership of the European Economic Community, 1961;
to withdraw British forces from East of Suez, 1968;
to expel 105 Soviet intelligence officers from the UK, 1971; and
to send a Task Force to the Falkland Islands, 1982.
