War poem (feedback really appreciated!)

I lately feel my sleep is light:
Thrashing, tumbling through the night,
My mind can hardly rest for long:
Repeatedly, I hear a song.

But more than that what occupies,
Preventing closure of the eyes,
Is ghastly thoughts inspired by sights
Of a land where gunfire fills the nights.

Acutely I can see grim scenes
Of children’s bodies piled––obscene
and vile; grotesque––they’re blown apart;
The chewing of a human heart;

Explosions tearing limb from limb;
A father, weeping, knows it’s him
Who must avenge with loaded gun
The murder of his only son.

Yet images of misery
And death become banal to me;
We’ve relegated to mundane
Agony, torment and pain,

And famine, genocide and war;
emotion stuffed inside a drawer;
Has psychopathy taken root,
which renders intervention moot?

What sinister thought vexes me
Is not a war across the sea,
Nor conflict in a place of sand,
Nor mustard gas in foreign land;

But rather what disturbs my slumber
Is peristent fear and wonder;
When I close my eyes what greets
Is red-starred tanks on tarmac streets;

A fire growing ever high
And wide; the cloud engulfs the sky;
The heat is overwhelming me
As burning skin is all I see;

Melting flesh and singeing hair,
The stench that whafts throughout the air,
Stifling my very breath;
Mercifully, enter Death,

Enter darkness, exit light.
What disturbs my sleep tonight?
