"American history is bogus"? I suppose none of use here have heard of the lend/lease program which was set up between America and the Soviet Union to supply Soviet soldiers with aircraft and weapons. More than $10 billion dollars (from the US alone, more from other allies) in weapons were supplied to the Soviets, including 14,000 aircraft.
Here is a partial list of what the allies (primarily America) supplied the Soviets during the war:
Bren Carriers - 2336
M3 Halftracks - 900
M3A1 Scout Cars - 3092
M3A1 Stuart - 1233
Valentine - 3487
Churchill - 258
M3A3 Lee/Grant - 1200
Matilda - 832
M4A2 75mm Sherman - 1750
M4A2 76mm Sherman - 1850
Half Tracks - 820
Light Trucks - 151,000
Heavy Trucks - 200,000

Ammunition and explosives supplied by the allies equaled about 1/2 the amount used by the Soviets during the war.
Others supplies,
229,000 tons of aluminium
2.3 million tons of steel
2.6 million tons of petrol
3.8 million tons of foodstuffs
56,445 field telephones and 600,000km of telephone wire
15 million pairs of army boots

America fed 6 million Soviet troops with 1 pound of food each day
It's easy enough to see that the Soviet Union was dependent on the allies for the weapons and materials to continue fighting the war, particularly after the crushing losses of such items in the opening months after the Germans attacked.
Tell me again how great the Soviet Union was, and how they were the ones responsible for winning the war against Germany.
