No child, but you do seem to have a bizarre theory that history is over and the possibility of major wars has ended because someone recently invented money and economics.
Try reading more extensively and you’ll see that technology has made mass warfare obsolete.
I have studied warfare for...oh, going on forty years, now...since my career Marine father brought the very young me to visit his first battlefield on Okinawa. Oh, I even have a PhD in modern European history, with a specialty in WWII logistics. And make my living teaching history.
And you? Oh, yeah. You post anonymously to an internet forum.
Stick to sports on television. That’s your speed.
