Could the Soviet Union compete with both the United States and a British Empire that did not decline?
Short answerThe Soviet burden would be formidable, but Britain would still move from empire toward a Commonwealth designed to retain trade benefits without paying all the costs of direct rule.
NotesThe British Empire would still move toward a Commonwealth even in a stronger postwar scenario. British discussions of dominion and Commonwealth structures predated the twentieth century's final decolonization wave. Britain could preserve access to trade networks while transferring much of the financial and military burden of direct rule. A Soviet naval competition would therefore face a British-led Commonwealth framework rather than an unchanged imperial system.
