Yeah, gp seem disconcertingly disconnected from the reality of Yemen, Syria or Palestine - just to mention a few places off the top of my head.
Despite any media hype, the world is more peaceful than ever, and a fewer % of people are living in poverty than ever.
Maybe they're exceedingly well connected with reality.
Looking at the angry headlines of the day is a very misleading way of understanding the world.
The first is scale. WWII scale was massive and considering that WWII was really just WWI-part2 its really just the continuation of the global struggle for power finally ended in ~1991.
Second is personal closeness. My relatives participated in WWII. My life is shaped by its outcome.
Third is ideological. WWII was a battle of world ideology. Fascism, communism, and liberal democracy.
For the places mentioned they do not have the same affect in my life. If those realities took place on a different planet I would not be the wiser.
I'm not sure I see how the soviet collapse and subsequent change of aggressors back to british/us in Afghanistan signified the end of the continuous confrontation between powers - rather than yet another shift.
I'll not go into what harvest one reaps from planting bombs and troops abroad, but at least in Europe we're hardly unaffected.
And while there was ideological propaganda and real differences then - there's religious fundamelism and fascism to go around still...
I'll definitely grant you that we're in a state of low intensity conflict over remote resources - and outsource much suffering - a state that seems stable for now.
