"No matter the outcome of this election, there will be blood – whether it be American blood on American soil or American blood on foreign soil, or both simultaneously. Fourth Turnings always accelerate towards a violent denouement, with an unanticipated number of deaths. Over 5% of the male population was killed in the American Civil War Fourth Turning, while 65 million people were killed during the WWII Fourth Turning. With the current level of killing technology, the potential number of casualties in a global conflict would be astronomical and inconceivable to average Americans."

I really don't buy the Fourth Turning thing.
World War 1 doesn't count and a financial crisis every 10-15 years going back 200+ years only counts when it lines up with their 80-year cycle.
The most turbulent period of recent American history was the 1960s, not the 1940s.
I think instead philosophical ideas trickles down through other fields and shape human behavior. The Dark Ages and Renaissance weren't 80-year cycles. Ultimately many particular factors combine to create specific events.
