The author is saying the Ukraine will lose without foreign supplies, just as Russia would have been defeated by Germany without US and British supplies and Allied attacks on Germany, including air raids that razed big chunks of German cities. For instance, the US sent 14,000 airplanes and 13,000 tanks to Russia, including ~5,000 of the Airacobra, a fighter first made in 1941.

[Most famously, Soviet dictator Josef Stalin raised a toast to the Lend-Lease program at the November 1943 Tehran conference with British Prime Minister Winston Churchill and U.S. President Franklin Roosevelt.

“I want to tell you what, from the Russian point of view, the president and the United States have done for victory in this war,” Stalin said. “The most important things in this war are the machines.... The United States is a country of machines. Without the machines we received through Lend-Lease, we would have lost the war.”

Nikita Khrushchev offered the same opinion.

“If the United States had not helped us, we would not have won the war,” he wrote in his memoirs. “One-on-one against Hitler’s Germany, we would not have withstood its onslaught and would have lost the war. No one talks about this officially, and Stalin never, I think, left any written traces of his opinion, but I can say that he expressed this view several times in conversations with me.”

, the United States provided the Soviet Union with more than 400,000 jeeps and trucks, 14,000 aircraft, 8,000 tractors and construction vehicles, and 13,000 battle tanks.

However, the real significance of Lend-Lease for the Soviet war effort was that it covered the “sensitive points” of Soviet production — gasoline, explosives, aluminum, nonferrous metals, radio communications, and so on, says historian Boris Sokolov.

“In a hypothetical battle one-on-one between the U.S.S.R and Germany, without the help of Lend-Lease and without the diversion of significant forces of the Luftwaffe and the German Navy and the diversion of more than one-quarter of its land forces in the fight against Britain and the United States, Stalin could hardly have beaten Hitler,” Sokolov wrote in an essay for RFE/RL’s Russian Service.]

[A total of 4,719 P-39s were sent to the Soviet Union, accounting for more than one-third of all U.S. and UK-supplied fighter aircraft in the VVS, and nearly half of all P-39 production.[62] Soviet Airacobra losses totalled 1,030 aircraft (49 in 1942, 305 in 1943, 486 in 1944 and 190 in 1945).[63]]
