He has videos on:
and a few more focusing on Ireland... his channel is here
I really enjoy enjoy his videos quickly summarizing wars and revolutions and while I expect certain shortcomings due to simply being summaries, are they accurate overall?
In the first 30 seconds of the World War II one he talks about the Great Depression (a deflationary event) and how it resulted in hyperinflation (which is as far as you can get from deflation as possible). The hyperinflation he is probably referring to is the Weimar hyperinflation in 1923, which had nothing to do with the Great Depression and which Sally Marks' "Myth of Reparations" definitively shows was deliberately caused by the German government to try to avoid paying reparations. So already, there is a major problem with his narrative.
The one on the Cuban Missile Crisis seems fine overall. Obviously I can't speak for the others.
