The argument is actually made on the basis of 450 years of quantitative data--in other words, interbellum periods are part of the data set. Indeed, interbellum periods didn't substantially exist until post-1815, so Lebow would probably argue that the fact that they even exist now buttresses his findings.

What he doesn't do, however, is code for war severity. And he only deals with major power wars.
