You said that the Smoot Hawley Act wasn't introduced until six months after the crash of 1929. If it wasn't introduced until then why does your article about it say that the House passed it's version in May of 1929? Which came first , May 1929 or October 1929?
Here's a chance to implement some bloviation reduction.
It doesn't matter when the SH Act was introduced because it couldn't have any effect until it became law - which was 1930.
The article you led off with many posts back asserted that SH was the main cause of the GD. Which is boolshite since it wasn't in existence until after the GD began.
See how easy it is to not make tedious response posts? Facts are useful that way.
