i was wondering about that, i mean technically it could be considered the last war because it was before the modern era (1900) and yes,i know about world war and etc but what i mean is that the mexican-american war was the last one that didn’t have a lot of planning into it, similar to wars in the older days,like there was no system control back then or like radio so technically, while not true, could it be considered “the last war of humanity”?
It’s just a name. I mean world War 1 is called “the war to end all wars” and then 10 years later we have another war, one simply called “the big one.”
