[I]n the course of the first half of the nineteenth century a moral revolution was completed in England; a revolution which was in the long term to e… - Correlli Barnett

Between 1946 and 1950, the most desperate period of the post-war export campaign and of national dependence on American loans and handouts, there were sixteen major strikes in British docks, cumulatively involving nearly 137,000 workers and losing a total of over 1,000,000 worker-days. Between 1950 and 1955...the dockers were out eighteen times playing the big matches and 168 times in instant and short-lived kick-abouts. The big matches drew onto the pitch a cumulative total of nearly 155,000 players, costing nearly 2,000,000 worker-days.
But mere statistics cannot properly record the ramifying harm inflicted on British industry and commerce by these repeated blockades. For they meant export delivery dates missed and foreign customers infuriated; factories held up for want of raw materials and equipment from abroad; wholesalers and retailers running out of imported foodstuffs; transport to and from afflicted ports backing up in standstill and confusion; telegrams and telephone calls crowding an out-of-date and already overloaded telecommunications net as victims of the blockades tried to sort out their troubles; and an immense waste of time and effort by ministers and civil servants in attempting to deal with the strikes and their immediate impact. More insidious still was the moral harm done to Britain at home and abroad by such spectacular mutinies, further helping to convey the impression of a nation without disciplined purpose, and instead blindly intent on self-mutilation.

How then was the Admiralty to find a fleet for Singapore, as had been repeatedly promised (though with waning conviction) to Australia and New Zealand before and since the outbreak of war with Germany and Italy? It went far deeper than a mere question of naval strategy and deployment. As Sir Samuel Hoare, the then First Lord of the Admiralty, had remarked to the 1937 Imperial Conference, "the very existence of the British Commonwealth as now constituted" rested on the ability of Britain to send a battlefleet to Singapore. But this in turn posed an even more profound question about Britain's very own existence as the centre of this oceanic empire, the immediate practical implications of which were so starkly confronting her leaders in the summer and autumn of 1941. For in retrospect it can be seen that it was an illusion for the British to believe that the Commonwealth and the Empire made Britain a great world power. Rather the strategic and economic balance sheet in 1941 demonstrates that the Commonwealth and Empire (with the notable exception of Canada and perhaps South Africa) were not an asset, but a net drain on Britain's strength; a predicament. For the imperial pink splashed across the map of the world in British atlases did not represent strength, as the British romantically believed, but one of the most outstanding examples of strategic overstretch in history.

Cobden in his boundless mid-Victorian optimism about free trade could no more have imagined such a plight than Adam Smith could have imagined refrigerated cargo ships bringing meat from the New World to undercut British livestock farmers. Perhaps their intellectual descendants today are at times too preoccupied with peacetime world trade and the advantages of economic specialisation between nations, to the neglect of the total-strategic implications in wartime of such specialisation. But at least Adam Smith himself recognised that, in his words, "defence, however, is of much greater importance than opulence".
