You can google, no? The impact of protectionism is pretty bad, when you hike up the tarriffs on products, that you dont even produce yourself. For example, exotic fruits were a big deficit. Also, nazis didnt kill everybody they conquered. Most factories in the east were re-tooled and slave labour was brought in. Basically, imagine Schindlers factory and now multiply it by X until you reach 1/4 of the labour.
