I would have to agree with Octospire. The west takes an undue amount of credit for ‘winning’ WWII. The lend lease program really didn’t pass as a percentage, that much equipment on the allies. The 50 destroyers lent/leased to the brits were of WW I vintage. It did allow the USSR to not have to concentrate on building small numbers of transport planes and utility equipment but rather concentrate on building their excellent stormovik (sp) ground attack plane and the steller T-34 tank.
By the time the US was ready to do some fighting it was mid -42 and they got their nose bloodied fighting in west africa as they did not care to learn the lessons the easy way from the other allies with 3 years of fighting experience. Moreover the initial daylight bombing raids over Germany in 42 early 43 were a disaster!
Dispite all the allied bombing, the germany GDP continued to INCREASE and only started to decrease when Germany started to lose France in mid 44.
I have said it many times, 9 out of 10 germans killed in the war were killed by russians. So that means the US, Britain, Canada, and all the rest get to split the other 10% of inflicted casualities and from that take credit for winning the war?
No doubt, without US industrial help the War probably would have ended in 1947 with the USSR controlling all of europe including France.
