In terms of foreign policy, there is much evidence to suggest that there was a shared set of views that were rooted in role of the recent history. Dennis Kavanagh and Peter Morris emphasise the importance of the second world war, and war time cabinet, in yielding a set of values that were shared amongst the major parties rooted in the events leading up to the war: "Atlanticism, the development of an independent nuclear deterrent, the process of imperial disengagement and reluctant Europeanism: all originated in the 1945 Labour Government and were subsequently continued...by its successors". However, there were some disagreement on areas of foreign policy, such as the introduction of the Commonwealth where  "Labour opposed the conservative 'imperial rhetoric' with the idealism of multicultural Commonwealth" or, in the same vein, decolonization, which became "an important theme of partisan conflict" in which Conservatives showed a reluctance to give back colonial possessions as well as the gradual process of independence.
