The argument "globalism didn't stop WWI" fails to examine the counterfactual, would WWI have happened without globalism. Did globalism tamper the forces of war, albeit failing to hold them back completely in the end?
The Bronze age collapse, so far as anyone knows, was due to invasion by "sea people". An invasion that they are documented fending off but struggling against for many years leading up to the collapse.
I could go on. The whole thing is just really unconvincing if you're not already predisposed to his conclusions.
