Max Sinister said:Yes... but when the Allies attacked Ploiesti, it just got into their reach, i.e. they had to fly over German-controlled territory. The Germans would have the advantage that the Turks and / or Persians probably wouldn't fight back, and since Russia doesn't expect an attack, they're screwed.
And about the Allies giving Russia the oil: I don't know when Russia started to get Lend-Lease help... did this happen in OTL before Hitler declared war on the US? I don't know how much gas the Red Army will need for their tanks... could be millions and millions of barrels...
The Russians will most definitely be petrified of an attack. German control of the MidEast loses Russia its main hold over Germany. The Russians will most definitely expect an attack, it is what they are preparing for.
The USSR's oil needs will be substantial, but US supply was massive, the US was the main oil produced at this time. Venezuelan production was also relatively substantial.
THe Soviet army was also still more horse than internal combustion engine driven
Ploesti and the Kirkuk fields are also in range of the Soviets, if the British have left anything of the Kirkuk fields.
