Who did this song?

Question

You go far across the ocean,
In a war that's not your own.
And, while you're winning theirs,
You're gonna lose the one back home.
Do you really think the only way,
To bring about peace,
Is to sacrifice your children,
And, kill all your enemies?
And, your money says "In God We Trust"
But, it's against the law to pray in school.
You say, "We beat the Russians to the moon,"
But, I say, "You starved your children to do it."
