God forbid. Newbie arguing with an administrator is utter nonsense.
And I agree it was not intended to be pleasant.
Back to topic.
Stalin did not, it was a Russian infantry man Vanya who did, despite the Soviet butchers, aka generals, outstanding efforts. Maybe not so very much on the Pacific, but Soviet European front effort exceeded anything that allies did.
The importance of lend lease is usually largely overcredited (Britain was issued 30bn, USSR just under 10) with the victory on the European front. Issued =/= received, one only has to remember the infamous caravan PQ13.
But nevertheless it would be wrong to underestimate lend lease's importance. Products (10mn pairs of boots; 100000 machine guns, 7000 aircraft, over 500 ships) and materials (2,5mn tons of steel; 0,25mn tons of Aluminium) received freed Soviet manufacturing capacities. By the way, I wonder how Mr. Engineer will like the fact that Soviet ace, Alexander Pokryshkin, fought in Aerocobra plane?
Also Lend lease deliveries were made during the crucial period of second half of 1942.
All of the above is more than enough to credit Allies with important economic help.
