". It is not true that Germany was dependent on oil from North Africa )."
Another half-truth and deliberate obstfication from Mr Denial:
On February 11, 1940, Germany and the Soviet Union entered into an intricate trade pact in which the Soviet Union would send Germany 650 million Reichsmarks in raw materials in exchange for 650 million Reichmarks in machinery, manufactured goods and technology.[50][52] The trade pact helped Germany to surmount the British blockade.[2]...................................................................
While some slowdowns and negotiations occurred especially during the early negotiations of specific orders,[3] the Soviet Union met most of its requirements under the agreement.[53] It became a major supplier of vital materials to Germany, including petroleum, manganese, copper, nickel, chrome, platinum, lumber and grain.[57]

Bear in mind what else was going on on the western front in 1939, 1940 and early 1941, while the Nazis were being supplied from the east by the Russians In that context, assuming for a moment that there was indeed a delay in opening the second front, this would then be just a tad more understandable.
