Song I wrote inspired by the war in Iraq

This is largely about American foreign policy and the war in Iraq. Why the hell do we constantly need to goto war? Imagine a world without war, and that's the theme of this song.

For the music, I'm thinking of maybe something very basic and bare, an accoustic guitar or perhaps just a piano? Tell me what you think, here's the words.

Imagine there's no heaven
It's easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today...

Imagine there's no countries
It isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace...

You may say I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will be as one

Imagine no possessions
I wonder if you can
No need for greed or hunger
A brotherhood of man
Imagine all the people
Sharing all the world...

You may say I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will live as one
