Why determining the Impact of Lend-Lease is so complicated (YouTube video)

We’ve had a number of debates over the years concerning WWII, and specifically what effect Lend Lease had on the Soviet war machine and where they would have been without it. This is a video from one of the channels I subscribe to that delves a bit into this question and explains why there isn’t a simple answer. https://www.youtube.com/watch?v=IJ9PiDvI4pY. My apologies to anyone watching it who has issues with accents…the guy doing this has a heavy German accent so you might find it hard to understand. I think you can turn on closed caption though if you have a real issue. Anyway, I thought it was interesting so figured I’d post it in case anyone else is interested.
