The debate about grand strategy in the Second World War has scarcely ended even in the 21st Century. The present study examines the classical issue of the grand strategy in Europe and the anti-Hitler coalition as concerns the US-UK-Soviet exchange about the Second Front. The great phenomenon of the Second World War was the creation of an unprecedented military alliance between the western powers and the Soviet Union. Due to mutual antagonism, inter-Allied cooperation during the Second World War was very complicated and at times extremely tense. Perhaps the most acute disagreement in the relationship between the Allies was the "Second Front" controversy. Despite desperate Soviet demands to open the Second Front as soon as possible, the Western Allies launched a massive cross-channel operation in the northwestern Europe only in June 1944. This thesis analyses the reasons why it took the western powers so long to organize and execute such an operation and its implications for the post-war order. The detailed analysis of the grand strategy during the Second World War is one of the ways to comprehend the violent 20th Century amid the carnage of the 21st Century and its own problems of grand strategy.
