Its into quaint, there have been plenty of times in history where countries either (a) didn't exist as they do today or (b) didn't have standing militaries.
The standing military the US maintains today only dates back to WWII, and is exactly what Eisenhower was warning us against.
Equipment complexity is theoretical at best. I'm not aware of a war between comparable militaries since WWII. My expectation is that if or when that happens, equipment ceases being the determining factor pretty quickly in favor of boots on the ground and logistics. History, at least, supports those being the deciding factors.
