I used to think WWI and WWII were the same war with the 1930s as sort of a halftime break. Actually, even though they may be very tiny, war never really stops, one war bleeds into another. But WWI differers quite a bit from WWII in that there was no bad guys in WWI, all sides were bad. It was simply a matter of the old hereditary families of Europe fighting one another for more territory as they had been doing for hudreds of years only on an industrial scale, and almost all over the globe.

WWII was must more of a good guy bad guy war in which the world’s democracies were fighting for their existance, most of hereditory rule having fallen away post WWI. It was a full bore industrial war in which whatever side was allied with with the US could not lose. Once, however, the A bomb came into play full bore industrial might lost its invincibility.
