George Peden is Professor of History at the University of Stirling and
the author of several influential studies of British public and military
policy at various times in the twentieth century. _Arms, Economics, and
British Strategy_ brings it all together into a detailed
reinterpretation of the period starting in 1904, the year that saw the
launching of the _Dreadnought_, the world?s first armor-clad battleship,
and finishing in 1969, when the British government committed its
independent thermonuclear deterrent to Polaris submarines.
The book is divided chronologically into six chapters, devoted
respectively to the periods before and during World War I, the interwar
period, World War II, and the nuclear and thermonuclear periods of the
atomic age. Each chapter discusses the policy makers of the time, the
technological shocks affecting the supply and demand for military
equipment, considerations arising from the state of the economy, and the
strategic context and repercussions. The common theme is the choices
that had to be made given ?the tendency for the costs of new weapons
systems to rise more rapidly than the national income? (p. 1).
In every society planning for the contingency of war is conducted under
conditions of great uncertainty, and requires competing interests to
overcome mutual suspicion and resistance. Without hindsight it is rarely
clear what distinguishes the national interest from special pleading and
conversely. One pleasing aspect of the book is the care with which Peden
exploits the knowledge gained from knowing what happened next without
using it to criticize unfairly the choices made by those who lacked the
benefit of experiences that still lay in the future. Not accidentally,
given this, the most difficult chapters are the last two; unlike the
periods ending in 1914 and 1939, the Cold War did not end in the
finality of an all-out conflict that proved the worth or otherwise of
the insurance policies taken out against it.
Peden keeps a range of targets in his sights. At the center is the
conventional wisdom on British military decline over the twentieth
century. This parallels (and takes some inspiration from) outmoded
stereotypes of Britain?s relative economic decline in portraying the
British armed forces as led by amateurs and equipped by conservatives
who failed to lift their eyes above the short term horizon. In
successive chapters Peden refutes the latter description, attributed in
various aspects to Corelli Barnett, Michael Howard, Mary Kaldor, and
Paul Kennedy, among others. In making his case he draws on official
statistics and documents in the national archives, the memoirs and
personal archives of the political and military actors, a vast secondary
literature, recent studies by his comrades-in-arms David French (on
military matters) and David Edgerton (on industry and science), and his
own previous research.
A theme of the interwar years that Peden rescues from undeserved
obscurity is that of economic stability as the ?fourth arm of defence?
(p. 132). In the late 1930s, Treasury officials argued that price
stability and the competitiveness of traded goods were an essential
element of the country?s capacity to wage war without external
assistance. This resonates to some extent with Mancur Olson?s finding
(in _The Economics of the Wartime Shortage_, 1963), based on the
experience of 150 years of warfare, that the best peacetime preparation
for war was to trade and specialize on the basis of comparative advantage.
The book is economically written, with an intimidating range of
reference. Beyond a clear division into parts, there is little help for
the reader in the way of signposting or other coordinates.
The context might have been enriched and simplified at the same time by
more explicit analysis of the rising cost of new weapons. Peden
demonstrates that the real unit cost of the major weapon systems --
airplanes, tanks, and vessels -- was increasing monotonically, implying
a rising share of national income required to build a given array of
units. This was one factor that drove successive British peacetime
administrations to shrink the numerical size of the armed forces. As
Peden points out, this does not mean that the armed forces became less
powerful militarily; the destructive power, and so military value, of
each unit also rose at a dizzying pace. The advent of the atomic bomb
did not mean more destruction, but it meant that the same destruction
that previously required mass bomber formations could now be achieved by
one plane and one bomb.
So, rising costs were not the sole factor in the evolution of public
choice in this field. A confounding factor was that ratios of military
value to the economic cost of weapon systems were also on an upward
trend. To complicate matters, value-to-cost ratios of different weapon
systems most likely rose at different rates, implying incentives to
substitute among them. Substitution would have been limited, however, by
further factors. One (to which Peden gives considerable attention) was
the changing patterns of complementarity among weaponry in different
uses. Another was the remorseless rise in the minimum efficient scales
of both production and use of military equipment. Finally, different
periods offered varying scope for mitigation of increasingly difficult
national choices through international trade and military collaboration.
To conclude, this is a rich, profound, sometimes difficult work of
historical scholarship that deserves to make a lasting impact in its field.
