Where are they?

Men of unknown ages
Crawl through muddy, blood soaked trenches in a faraway land
They climb out the trenches over body part infested swamp
Under the fire of snipers
They finger triggers, grenades, machine guns
Commit murder every time they act
According to the orders given
By cocktail, suit wearing cowards
Who sit in their white towers
That's what the world is made of
Sadly, that's all the world has ever been
Where are the heroes?
Where the men and women
Who build life
Where are they?
