Here's a poem by Wilfred Owen, the British soldier who fought in France during WWI.  He died a week before the end of the war, but his poetry was published and made him immortal.  This is a poem which denounces the political control of old men on the eve of WWI, a ruling clique which eagerly sacrificed the youth of Europe in order to pursue their own (perceived) interests. A fitting piece considering the recent events in Iran. Enjoy:

Parable of the Old Man and the Young

So Abram rose, and clave the wood, and went,
And took the fire with him, and a knife.
And as they sojourned both of them together,
Isaac the first-born spake and said, My Father,
Behold the preparations, fire and iron,
But where the lamb for this burnt-offering?
Then Abram bound the youth with belts and straps,
and builded parapets and trenches there,
And stretchèd forth the knife to slay his son.
When lo! an angel called him out of heaven,
Saying, Lay not thy hand upon the lad,
Neither do anything to him. 
Behold! A ram, caught in a thicket by its horns,
Offer the Ram of Pride instead of him.
But the old man would not so, but slew his son,
And half the seed of Europe, one by one.
