there were plenty of good things said about Stalin in 1943.
Fact is trade protectionsim did make WW2 more likely as protectionsims was one of the causes that made the economic downturn of 1929-1930 a great depression.
the causes of the Depression were the following:
Stock Market Bubble and Crash
Smoot Hawley
Tax increase in 1930
Gold Standard
Fed Reserve actions
none alone would have caused it.
Nonsense.
The fact is, trade collapsed simply because consumers couldn't afford to pay the higher transportation costs on imported items. Heck, it was even difficult getting domestic production going because many consumers couldn't even afford that.
