Since you've successfully moved into the blatantly absurd, how about I just let Captain Darling and General Melchett explain how the period before the Pax Americana worked. First, WHAT the rich were fighting over:

And how it affected normal people:

My grandfather explained this in much harsher terms to me (he's dead now, even though he got past 100 years), with explicit mention of which of 2 options is the better one: killing 100 people in your own city or returning to this situation again. He was a baby at the end of WW1 and lived through (with kids of his own) WW2.

(but even that beats how Iran's islamic government treats it's own citizens. Did you know primary school children make excellent demining equipment, and on top of that make very cheap poison gas detectors? The islamic mullahs sure do: https://en.wikipedia.org/wiki/Plastic_key_to_paradise )

I've a friend up the coast, nearly 100 now, a ham operator who used to relay space shuttle calls, former operator in PNG, British soldier during the Mau-Mau uprising.

Back in the day, during WWII, he was defusing bombs and mines while a young boy scout.

So, you know, not just Iran - the UK also.

Ah yeah the US would never demand young volunteers to be fed to the meat grinder

They would compel them, by law, to be fed to the meat grinder. And not to defend their homeland, but to murder civilians in another hemisphere, and apparently i must remind you, TO THE TUNE OF 4,500,000 DEAD CIVILIANS IN KOREA AND VIETNAM ALONE.
