Ironic considering that FDR's economic reforms were openly modeled on fascist Italy, and FDR was on good terms with Mussolini. He was also in the process of following Mussolini's lead and attempting to overthrow the American institutions that were in his way. He had already gone out of his way to install a KKK member on the Supreme Court, and was planning to double the size of the Supreme Court if they wouldn't accept his unconstitutional changes.
The article even admits this by quoting articles written at the time that were calling for a fascist takeover of the country and supporting FDR's goals in this direction. Many were terrified that this was indeed what FDR was planning.
This whole thing about Butler coming out and saying it was the other way around, and fascists were tying to overthrow FDR was just a political point scoring. This article even admits that if something like that even happened it was at best a “a cocktail putsch.”
This is just the typical rewriting of history from people who refuse to face their ashamed past.
