did not bring inter-service rivalries to an end. Healey , who was secretary
of state for defence throughout the period of Labour government from
1964 to 1970, may well have preferred divided counsels, since he was
intellectually self-confident, had studied strategic problems prior to
taking office, and had no reason to encourage united opposition within
the ministry to his ideas.

Churchill, Eden and Macmillan were all prone to taking a hands-on
approach to defence, sending personal minutes to ensure that their views
were being acted on. Much of the policymaking was conducted infor-
mally, with the Cabinet’s Defence Committee and even more the Cabinet
itself being involved at a late stage, often only to give authority to deci-
sions that had already been taken and to ensure that information reached
everyone concerned through the circulation of minutes. The way in which
the decision to develop the hydrogen bomb was taken exemplifies this
point. After hearing of the first American test on 1 March 1954 Churchill
summoned Plowden, chairman-designate of the Atomic Energy
Authority, which was about to take over responsibility for nuclear energy
from the Ministry of Supply, to advise on what would have to be done to
develop and manufacture these new weapons. After Churchill had taken
the decision to go ahead, the Cabinet Secretary, Sir Norman Brook,
called a meeting on 12 March to discuss the implications for foreign
policy, defence strategy, the size and shape of the armed forces, civil
defence policy and the atomic weapons programme. Those present were
Plowden; two scientists, Sir John Cockcroft, the director of the Atomic
Energy Research Establishment at Harwell, and Sir William Penney, the
director of the Atomic Weapons Research Establishment at Aldermaston;
and three officials from the Ministry of Defence. Penney explained the
destructive power of the hydrogen bomb, and Brook briefed the Prime
Minister on the policy adjustments that would be required. These matters
were then discussed by senior ministers in the Defence Policy Committee,
which was advised by the Chiefs of Staff, who in turn sought advice from
Plowden, Cockcroft and Penney. Both scientific and professional advice
followed on from Churchill’s original, political decision after his discus-
sion with Plowden in March.
