Yes! WWII remains the archetype of war for the U.S. military, to the detriment of preparing for the many other ways war is fought. https://twitter.com/H_BrandonMorgan/status/1253939763972694017

One manifestation of this is the U.S. defense community's obsession with creating new terms to describe forms of conflict that don't fit their narrow paradigm of what war ought to be:
irregular, hybrid, asymmetric, or unconventional war, military operations other than war ...

As SecDef Gates noted (citing Colin Gray) war does not fit into "neat, tidy boxes"

Instead of coming up with new terms every time an adversary does something that doesn't fit our narrow conception of war, our concept for what "war" is needs to adapt to meet reality.
