It cannot be overstated how important US shipments of weaponry, industrial equipment, and supplies were to the Soviet Union when they began to arrive. Without them, Moscow would've fallen and the Soviets along with it. The relocation of the Soviet industrial base would have never been managed without the arrival of
Studebaker trucks, a truck which the Soviets were so impressed with, they adopted its design as a general purpose off-road, all-weather truck into the
ZiL-157. And that was merely on the Soviet side of things. For the rest of the Allies, the US sent all manner of foodstuffs and armaments over in ships; the US sent over so much food to Europe that they imposed rationing on the US citizenry. During that period the US food production industries invented what is now derided as "fake food" just so people could eat
something; things like Spam and Kraft processed cheeses. To say that the US "didn't look at Europe" is as atrocious a reading of WWII history as "America did everything fuck all y'all."
