The policy swings that have marked British policy have resulted, to a large extent, from disagreement about the answers to these questions. Thus, in the immediate post-war years, the British Government eschewed committing land forces to defend Europe because such a policy did not work well in 1914 and 1940. Then, the policy was to retain a robust presence in the Middle East where, it was thought, Britain could contribute more to defending European and British interests than sustaining a significant presence on the European continent. Roughly a decade later, the UK reversed this by committing several divisions on the Rhine. The Falklands War made British policy-makers rediscover expeditionary capabilities and the need to be able to do things other than NATO-specific missions, causing the UK to reassess once again what kind of military it needed.
