The Russian army

yes
'keep of the grass'

we can put the effort in, because we believe in the innate goodness of spirit of mankind.
this belief is misplaced peace can only occur at the end of a gun, and only temporarily at best.

the story of the alligator and the mouse crossing the river springs to mind.

I think that sooner or later humans are going to comprehend that being governed by the more brutal, violent side of our nature hasn't helped humanity as a species. And that, if we want real progress we'll find ways to harness & control our violent side, channel it into something more useful. That energy could perhaps be used instead to create, invent far more useful & benevolent things rather than who's got the biggest gun, & who can kill more people.
 
And it may be that you're right & that will only happen at the end of a gun, at least initially. But while we may be capable of enormous stupidity, we're also capable of its opposite & that's what may one day lead us onto a different path. it might be something which must be taught in schools eventually but we need to start putting more effort into finding ways of changing for the better.
As long as we don't annihilate ourselves & our world first.

that sounds too hard.
