I think my comment about lend lease isn't controversial. From https://en.wikipedia.org/wiki/Lend-Lease :

"According to the Russian historian Boris Vadimovich Sokolov, Lend-Lease had a crucial role in winning the war:

    On the whole the following conclusion can be drawn: that without these Western shipments under Lend-Lease the Soviet Union not only would not have been able to win the Great Patriotic War, it would not have been able even to oppose the German invaders, since it could not itself produce sufficient quantities of arms and military equipment or adequate supplies of fuel and ammunition. The Soviet authorities were well aware of this dependency on Lend-Lease. Thus, Stalin told Harry Hopkins [FDR's emissary to Moscow in July 1941] that the U.S.S.R. could not match Germany's might as an occupier of Europe and its resources."

So I assume I am getting downvoted because I said the Russian were brave in WWII? That is hard to deny, isn't it? Lots of German accounts praise the near suicidal bravery of Russian soldiers in WWII[1]. But I get that isn't a very popular thing to say given the monstrous war crimes that the Russian state is currently committing.

[1]Admitedly some of this bravery may have been due to NKVD stationed behind them with orders to shoot retreaters.
