The major problem I see, is that every major power uses propaganda to their benefit, yet even highly intelligent people often don't see the propaganda of their native (or chosen) home.
I see the propaganda of China, Russia as well as the one of the US and Europe.
There are no white, selfless knights around. There never were.
Does that mean that nothing matters, that (subjective) morale suddenly is meaningless?
Of course it doesn't!
But it puts "them vs us" into perspective.
Humans are humans and act like humans all around the world.
