it would have severely damaged the ethical basis of its struggle against Nazi Germany. According to Heinz Richter, Churchill tried through the campaign in Greece to influence the political atmosphere in the United States and insisted on this strategy even after the defeat. According to Keegan, "the Greek campaign had been an old-fashioned gentlemen's war, with honor given and accepted by brave adversaries on each side" and the vastly outnumbered Greek and Allied forces, "had, rightly, the sensation of having fought the good fight". It has also been suggested the British strategy was to create a barrier in Greece to protect Turkey, the only (neutral) country standing between the Axis bloc in the Balkans and the oil-rich Middle East. Martin van Creveld believes that the British government did everything in their power to scuttle all attempts at a separate peace between the Greeks and the Italians, in order to ensure the Greeks would keep fighting and thus draw Italian divisions away from North Africa. Freyberg and Blamey also had serious doubts about the feasibility of the operation but failed to express their reservations and apprehensions. The campaign caused a furore in Australia, when it became known that when General Blamey received his first warning of the move to Greece on 18 February 1941, he was worried but had not informed the Australian Government. He had been told by Wavell that Prime Minister Menzies had approved the plan. The proposal had been accepted by a meeting of the War Cabinet in London at which Menzies was present but the Australian Prime Minister had been told by Churchill that both Freyberg and Blamey approved of the expedition. On 5 March, in a letter to Menzies, Blamey said that "the plan is, of course, what I feared: piecemeal dispatch to Europe" and the next day he called the operation "most hazardous". Thinking that he was agreeable, the Australian Government had already committed the Australian Imperial Force to the Greek Campaign. Impact on Operation Barbarossa In 1942, members of the British Parliament characterised the campaign in Greece as a "political and sentimental decision". Eden rejected the criticism and argued that the UK's decision was unanimous and asserted that the Battle of Greece delayed Operation Barbarossa, the Axis invasion of the Soviet Union. This is an argument that historians used to assert that Greek resistance was a turning point in World War II. According to
